It says loading is starting but doesn't load. What to do if Windows does not start. Video: If the computer does not turn on, what to do

There is probably no need to explain that situations when the computer does not boot occur quite often. There may be a myriad of reasons that led to this. Now we will try to figure out why such situations arise and how to deal with them. Let's look at desktop computers rather than laptops, although in some cases the methods for solving the problem may be very similar.

Causes of download problems

First of all, in the question of why the computer does not boot, you need to understand that among the main reasons there are two main ones: physical damage to the components of the computer system and a malfunction of the software (in this case, Windows).

Both can cause serious problems. Let's look at the most common causes of failures and figure out how to eliminate the consequences.

Consequences of physical impact

As for damage to physical components, first you should pay attention to the initial stage of booting the PC. Probably everyone knows that when turned on, the system unit makes a characteristic sound (a single squeak). This indicates that all hardware components are in order. True, this is not always the case. The fact is that a hard drive failure is detected only after startup (the system does not see it).

Sometimes the system speaker may emit short and long squeaks. This is already worse. This can only mean one thing - some component is not working, has failed, or is simply incorrectly connected to the motherboard. The signals may vary for different BIOS versions. But all of them may indicate malfunctions in the operation of RAM, video card, central processor, etc. In some cases, there may be no signal at all.

In this case, it is recommended to remove the system unit panel and check whether all components are connected to the motherboard. It may well be that the device does not work not because of failure, but because the corresponding cable is damaged. Naturally, it is not possible to determine such a malfunction yourself, so you will have to turn to specialists.

There are often cases when the computer does not boot even when turned on. There may also be enough reasons for this. It is very likely that there is simply no power supply. It is worth checking the outlet or uninterruptible power supply. Sometimes, when a large number of electrical appliances are plugged into an extension cord, protection and much more may be triggered. You can check the battery that is installed on the motherboard. It is very possible that after replacing it, turning on and booting the computer will go as usual. Often no one pays attention to this, nevertheless the fact remains a fact.

In general, you should immediately check all cables, sockets, extension cords, etc. Maybe this is really the reason. That’s why it turns out that nothing starts, nothing loads, the computer is black and shows no signs of life.

Crash systems

Of course, you can replace the hardware, but with the operating system itself the situation is much worse, because no one obviously wants to reinstall the system, format the hard drive or partitions, which will entail data loss.

There are just a lot of reasons why Windows might crash: a sudden power outage, incorrect shutdown or shutdown, a software failure, the presence of viruses, damage to the hard drive, etc. The list is endless.

As for physical damage to the hard drive, the severity of the problem can only be determined after full testing of the surface and contacts. If it burns out, you know, you’ll have to shell out money for a new one, there’s nothing you can do about it. If the damage is minor, you can try to restore the damaged sectors. This will be discussed a little later.

Basic methods to correct the situation

As is already clear, in terms of hardware failure, when the computer does not boot, the black screen hangs constantly, the system unit does not make a sound, the solution would be a complete test of all components. It is very possible that reconnecting or replacing some of them will clarify the problem.

It is worth noting that in some cases, when the system does not detect the hard drive, the most trivial situation may occur. In the BIOS, the boot priority can be set to, say, CD/DVD/ROM first, the second device is a USB drive, etc. It is clear that when media of this type is inserted, the system will display a message stating that this is not a system drive.

It also happens that the computer does not boot from the Windows installation disk. Here you will have to check the disk itself. It is very possible that there are some scratches or other damage on it. By the way, perhaps the drive itself is damaged and simply does not work.

Now a few words about how to correct the situation when the computer does not boot, Windows 7 does not start, and in general it seems that nothing can be done.

Let’s say right away: don’t despair and panic. Bill Gates is not a stupid person at all. When creating his system, he left loopholes to restore the functionality of the operating systems, and today there are quite a lot of methods that allow you to quickly and effectively apply measures that can, so to speak, breathe new life into the system. Below we will describe the most common problems and methods for eliminating them specifically from the point of view of the Windows software shell.

Loading Last Known Good Configuration and Restoring the System

As a rule, even after very serious errors in the operation of Windows 7, as they say, it simply does not give up. On reboot (if everything is fine with boot records), testing occurs, and then in most cases a message is displayed about possible boot options, including loading the last known known configuration.

This happens because the system, as it were, remembers its last working state and offers to go to it, bypassing all the changes made before. In 90% of cases this helps. However, it also happens that the computer does not boot even if Windows self-healing, and the user eventually receives a message that such a configuration could not be loaded.

The same applies to using system restore, which may be offered when Windows starts. Sometimes it helps, sometimes it doesn't. In principle, both services are very similar. In this state of affairs, more effective measures will have to be taken.

Safe mode

Many users, faced with a problem, for example, when the computer does not boot after updating Windows 7, clearly underestimate the benefits of safe mode, but it allows you to gain access to a fully functional system and fix many software errors.

To load safe mode after the system starts, you need to press and hold the F8 key. When the system boots, we can take care of our problem. In this case, you can check all the hardware components for functionality and the presence of the appropriate drivers, run a disk check for errors, and finally begin restoring the system.

System Restore

First of all, using the control panel, you need to go to the “Backup and Restore” section. It can also be accessed from the main Start menu under All Programs/Maintenance. Here you need to select a checkpoint (the last one created or one of those present in the list) and start the process itself. This, of course, can take quite a lot of time, but if you don’t want to reinstall, you’ll have to be patient.

Now let's say that after the updates the computer does not boot. In the same control panel, if you go to Windows Update, you can view the update log, in which, in fact, you will need to delete everything that was installed before the system crash, no matter whether these updates were installed automatically or in manual mode.

In many cases, this approach allows you to revive Windows without resorting to more serious methods, which not every user can handle.

Using the Recovery Console

If the above method does not produce results, you will have to use other methods. One of the most effective and radical methods when the computer does not boot is to use the recovery console, which is available either on the Windows 7 installation or emergency recovery disk.

To use such disks, of course, you should make the appropriate boot priority settings in the BIOS, indicating the CD/DVD-ROM first in the list.

The boot menu will show a "Welcome To Setup" screen, after which you will need to press the "R" key to go directly to the console (command line). It is worth considering that if more than one operating system is installed on the computer, folders with files will first be shown, and then a request will follow which system the user wants to work with. Now you just need to enter the number corresponding to the number of the selected system. Next, you may be asked to enter the administrator password, provided that you have one. Now about the teams. What and how to enter and what to use, we will now figure it out.

Recovering the Boot.ini file

As a rule, one of the reasons for a system crash is damage to the Boot.ini boot file, which is responsible for loading the system. To restore it, almost all systems use a tool called Bootcfg. Bootcfg/Rebuild is entered on the command line (not counting other tools for scanning its entries, redirecting actions, adding identifiers, etc.). It seems that, apart from the main recovery command, the average user does not need anything else.

Recovering the Master Boot Record

The master boot record contains tables of all logical partitions of the hard drive. The so-called primary loader places the active and boot sectors in the tables, after which, in fact, the system starts. If the boot record is damaged, the active sector simply will not be able to start the system.

To restore in this case, use the Fixmbr command, after which you enter the qualified name of the disk or partition. In the case of drive C, the command will look like Fixmbr\Device\HardDisc0.

Recovering the boot sector of the hard drive

The boot sector is a small partition on the hard drive for storing data in FAT32 or NTFS file systems for booting. If it is damaged, use the Fixboot\c: recovery command (provided that the operating system was installed on drive C).

Quick system reinstallation

Again, let's consider a situation where, after updating Windows 7, the computer does not boot, and the system simply does not want to start. As a last resort, you can use the so-called quick reinstallation of the system in the same folder where the previous OS was installed. In some cases, this may correct errors.

After the system starts from the disk, the license agreement window will appear. You can agree to the terms by pressing the F8 key, after which you will be asked to select an installation method. Key "R" - restore the existing version, Esc - cancel the restoration and go to a new installation. In most cases, recovery proceeds without problems.

Virus check

Now a few words about another unpleasant situation, when the system does not start and the computer does not boot. A black screen may be the result of spontaneous viruses that either prevent the system from booting or change boot records.

In this case, it is recommended to use utilities such as Kaspersky Rescue Disc or Dr. Web Rescue Disc. As is already clear, such programs start directly from the optical disk, but, what is most interesting, they are loaded even before the Windows OS starts. They have a graphical interface, so working with them is not difficult. It should be noted that in 99.99% of cases, such applications remove even those viruses that are simply impossible to remove using standard scanners installed on the system. After all, they can “hang” even in RAM. At the end of the check, the computer terminal is rebooted, and, hurray, the system works again as if nothing had happened.

Conclusion

So we looked at the question of what to do if the computer does not boot. It seems that some solutions to this problem will be useful to many users. Of course, it’s quite difficult to say right away, right away, why a computer or operating system won’t boot. But if you conduct a comprehensive test and find out the cause of the problem, then you can choose the most appropriate method to correct the situation.

Situations often arise when the Windows XP operating system suddenly stops loading. There can be many reasons for this, and each specific problem requires an individual solution. However, if the user knows why the computer may malfunction, then he can easily solve the problem on his own. All possible reasons for failure can be divided into two groups:

Hardware - something has broken in the inside of the computer, and Windows no longer works;
Software - software errors have arisen in the OS itself that interfere with the correct operation of the system;

It is also worth paying attention to at what stage the OS does not load, that is, what manages to appear on the screen, and after what particular event you detect a failure. In this case, we will consider the situation when Windows XP no longer starts after the splash screen appears.

What can be done

The very first method you need to resort to is loading the system's last known known configuration. After all, the cause of the malfunction may simply be that you, for example, installed an incorrect program or driver on your computer, due to which the OS does not load normally. Accordingly, for the system to operate normally, you need to return it to the moment when these tools were not installed. There is a special section in the system registry HKEY_LOCAL_MACHINES\SYSTEM\CurrentControlSet, where information about the last problem-free boot is recorded. It is with the help of this partition that Windows will determine the last known good configuration and boot based on it.

Another option is to run windows XP in safe mode.

With this method, only the minimum required set of software tools for running Windows is loaded, and none of the auxiliary programs are loaded.

If you were unable to boot your system as usual, but it booted into safe mode without any problems, this already means that you most likely recently installed some software on your computer that is causing your system to fail. starts.

After starting the computer in safe mode, you should restore Windows XP. To do this, you need to run the recovery utility, which is located in the All Programs/Accessories/Utilities/System Restore directory. It takes so-called snapshots of important system files, and saves the resulting information in the form of restore points at which the system boots normally (more precisely, it booted before the problem occurred). Points can be created manually, but periodically they are created automatically (for example, after installing new software). You need to select the desired point and then start the recovery process. Upon completion, the computer will restart.

If all else fails

If previous attempts have failed and your system still won't boot, your last resort may be to restore your system using the installer. In order to do this, you will need an installation disk with Windows XP. Insert it into the drive, enter the BIOS and set it to boot from it. You can also use a USB drive. If a window appears on the screen asking you to press any key to continue working, then do just that. The installation window for the Windows XP operating system will appear. You will need the first item, by selecting which you will begin installing Windows XP on your computer. First of all, a license agreement will be displayed on the screen, which you must accept, otherwise you will not be able to install the OS.

In the next step, the message “Searching for previous versions of Microsoft windows...” will appear at the bottom of the screen. Thus, the program determines what it needs to do next - install the system on the computer or launch a recovery mechanism for an already installed OS. There is one rather important nuance here - for the recovery procedure to be successful, you will need a disk with exactly the same copy of Windows that you had previously installed. This is due to the fact that each operating system has its own serial number, which during the installation process is also checked for compliance with the previously installed copy.

The computer does not boot. There is an image.

The computer does not boot. Disconnect flash drives connected to the computer, remove the DVD/CD disk from the DVD/CD-rom (if any), disconnect unnecessary peripherals, printer, scanner, etc. Let's check. If the download starts, then we turn on the disabled equipment one by one, find out what exactly affected the download, and fix it. Did not help? Go ahead.

Go to BIOS (Del; F2), set boot priority. A hard drive must be installed.

1) It is necessary to check the nature of the image on the screen.

If the screen is black, then see the article “The computer does not boot. No image“, if the background is black, but there are entries on a black background, then this article is for you. The most common is the appearance of the inscription: press f1 to continue. As a rule, you can press F1 and the computer and operating system will boot. And in order to fix the problem, you need to pay attention to the error when loading. The most common ones look like this:

A) cmos date/time not set or cmos battery low

Low battery. Signs: The time and date on the computer are constantly getting lost. You need to buy and replace a cr2032 battery.

B) cpu fan error.

Literally this means the following: an error in the operation of the processor fan, press “f1”. You need to open the cover of the system unit and look at the condition of the processor cooling cooler. The error means that the fan speed has decreased or it does not work at all. Prevention is usually sufficient. See the article “not downloaded.” computer. No image." Or replace the processor cooling cooler along with the radiator.

B) no keyboard detected.

Keyboard not detected. Reconnect the keyboard if it has a USB interface. If PS\2, then first you need to turn off the computer completely, then reconnect.

D) no hard disk is detected.

Hard drive not detected. Go to Bios and check if the hard drive is in the list. There are 2 hard drives in the photo.

If not, we try to reconnect the hard drive, connect it to another Sata interface, if the hard drive is also not visible, then most likely it has “decided to live for a long time”, we change it to another one. We can also diagnose the hard drive using the MHDD program; there is a separate article on this topic “hard drive diagnostics”

D) cmos checksum bad/error.

I also recommend going into the BIOS. Typically, when you boot your computer, you need to press the Del key, sometimes F2, depending on the hardware manufacturer. Restore date and time settings, load optimal settings (restore to default).

Note: Pay attention to the operating parameter of the Sata controller. If you set the default to Ide, and the operating system was installed in ahci mode, you will see a “screen of death” upon boot. You need to return it to the mode in which the operating system was installed.

2) If these steps did not help.

Computer won't boot? and you see the operating system screensaver loading and then nothing happens, then you need to diagnose the hard drive and RAM. If the hardware is working properly, you may have installed an incompatible driver or program - you can try logging into safe mode (usually press F8 several times during boot) and remove this software or driver.

You can also try loading the “Last Known Good Configuration” with working parameters.

If this does not help, you need to create a bootable USB flash drive, boot from it and start installing the operating system, try to perform a recovery. Restoring the last save point.

If the image is something like this:

You need to restore the windows bootloader. We tried system restore, didn't it help? Go ahead.

3) These steps did not help?

You need to reinstall the operating system. You can do this yourself, based on my articles on installing Windows, or you can also order a paid service. See install/reinstall windows in Kazan price.

Reasons for windows 7, 8 and 10 if the OS does not load

Most of the capabilities that the average owner of desktop computers and laptops use are available to humans thanks to the use of special operating systems on the equipment. The most popular OS is a product from Microsoft. Therefore, if Windows 7 or one of the other OS variants does not load, the user faces serious problems.

There are many reasons why Windows 10 (7, 8, XP) does not load. Often in this case, an unpleasant situation is accompanied by a specific error message. But what to do if Windows 10 (7, 8, XP) does not load on a laptop or regular PC without such messages? There are several universal treatment methods that can lead to a way out of this situation.

Selecting the download type

This is the simplest fix method if Windows 7 or another type of operating system from Microsoft does not load. What you need to do:

Start rebooting the computer.
Press the “F8” button.
In the proposed list, select the launch item with the most successful configuration.

In some cases, this action is quite sufficient when Windows 7 (8, 10, XP) does not load.

Windows Recovery

So, windows won't load. You can try to return Windows to full functionality using the recovery menu. To do this, of course, you will need to have a boot disk with the desired OS option on hand. What actions should the user take in this case if Windows 7, 8, 10 and XP does not load:

Insert the source into the drive.
Change the priority in BIOS. That is, the operating system should not be launched from a hard drive, but from a DVD-ROM.
After starting the process, you will need to press the “R” button.
Select the option to restore.
Wait for the results. Restart the equipment one more time. Windows XP (7, 8, 10) still won't load early? Next option.

If previous operations have been carried out, but Windows 7 still does not boot, you can try to restore it directly using the tools of the operating system itself. It's quite simple:

Pressing the magic button “F8”.

Selecting further boot in security mode.

Obtaining limited access to the operating system.

Making the transition: “Start” - “Standard” - “Service” - “Recovery”.

An attempt to return the OS to an earlier state that was stable.

Naturally, at the end you will need to restart the computer to check whether Windows 10 (7.8, XP) does not load or whether the problem has been successfully resolved?

Boot file disinfection

If Windows 7 does not boot after updating, then the possible cause of the problem lies in a damaged Boot.ini boot file. To fix the problem you will need to follow these steps:

Start the PC using the same external source.
In the recovery menu, go to the command line.
Enter the phrase “Bootcfg/add”.

Wait for the process to complete and initiate another reboot to check whether Windows 8 or its equivalent of a different version does not load, or whether the treatment helped in this predicament?

Boot record defect

Another option for trouble with Windows. Windows won't load? The boot record may have become corrupted. In this situation, you will need to repeat almost the entire procedure described in the previous paragraph, but enter a completely different phrase into the command line. Namely: “Fixmbr\Device\HardDisk0”.

Perhaps this action will be quite enough when Windows 7 does not load and freezes on the logo.

Damage to the boot sector on the hard drive

This nuisance can lead to a situation where, for example, Windows 7 does not load beyond “Welcome”. Here the treatment is also quite simple - the steps are repeated by running the command line from the computer user, into which you should type “Fixboot” and then the letter that is responsible for the hard drive partition where the installed OS version is located.

Quick reinstall

Sometimes, if the computer does not boot beyond the Windows 7 splash screen, only reinstallation can help. But it is not at all necessary to launch a full-fledged procedure that lasts quite a long time. You can speed up this process. This is a very powerful treatment tool as it can deal with most of the troubles that arise.

What is required from a person:

Start again from the boot disk.
Press the “R” button, then the “Esc” key.
Select quick reinstallation of the operating system.

It is important to understand that this procedure can only work if identical versions of the OS are located on the disk and hard drives. That is, if, for example, Windows 10 does not boot after the update, but you should not try to quickly reinstall it using a boot disk with Windows 7 or 8 for this purpose.

Conclusion

A special case of this situation may be a constant automatic reboot of the OS. Naturally, this option excludes the possibility of any therapeutic processes. To break this sequence, you will need to press the “F8” button the next time you start the system and go to the “Advanced parameters” menu. After this, disable the OS reboot procedure and if failures are detected. Well, then you can use one of the treatment options described above.

All described methods are universal. That is, they are recommended to be used only when it is not possible to accurately determine the root cause of the malfunction. Most often, the user can see a message on the monitor screen indicating a specific error code. And each of them has their own method of correcting an unpleasant situation. Most of them can be easily found on this Internet resource dedicated to answering questions related to OS damage from Microsoft.

The computer turns on, but the operating system does not start: possible causes and solutions to the problem

Unfortunately, sometimes you can encounter quite serious problems with turning on computers and starting operating systems, although until a certain point there were no signs of trouble. It happens that the computer does not turn on at all, but most often the computer turns on, but the operating system does not start. It is these situations that will be discussed further. Let's look at questions related to why the computer won't boot and what to do in such situations. There are several universal solutions here.

The computer turns on, but the operating system does not start: reasons

Among all the possible situations when failures occur at the loading stage, several typical cases can be identified.

There are three options:

a black screen appears;
Blue screen BSoD occurs;
The operating system starts, but cannot fully boot.

In the first case, when the computer does not start (the boot does not turn on), messages may appear on a black screen indicating physical or software problems. In the simplest case, when nothing serious happens, the system may report that, for example, the keyboard is missing (for desktop PCs). The simplest solution is to connect it and reboot.

If the computer turns on, but the boot does not start, and instead warnings about software failures or missing files appear on a black screen, there can be many reasons for this system behavior. Among them, first of all, we can highlight problems with the hard drive, damage to the operating system (accidental or intentional deletion of system components or registry entries), exposure to viruses, incorrect boot sector entries, RAM conflicts, etc. By the way, if a blue screen pops up, this mostly applies to the RAM or recently installed device drivers, which cause conflicts not at the software level, but at the physical level.

What to do if the computer does not boot and the operating system does not start for the above reasons? Depending on the situation, there are several solutions. To an uninitiated user, they may seem quite complicated, but in certain situations only they can be used to resuscitate the system. Therefore, you will have to spend both time and effort.

The computer turns on but does not boot: what to do first?

So, let's start with the simplest thing. Let's assume that a short-term technical failure has occurred in the system, for example due to incorrect shutdown or power surges.

As a rule, almost all windows modifications used today usually automatically activate system recovery upon restart. If this does not happen, before starting the system you will have to use the F8 key to call up the additional boot menu (a different method is used in Windows 10).

The computer turns on, but the operating system does not start? There's no need to get upset. Here, in the simplest version, you can select the line to load the last working configuration. If everything is in order with the system components, the system will boot without problems. If this does not help, you will have to use the troubleshooting section, and sometimes even trying to boot into safe mode may be successful.

Possible viral infection

Unfortunately, viruses can also cause such situations. What to do if the computer does not turn on? Ways to solve this particular problem boil down to using a powerful anti-virus scanner, which could check for threats even before the OS itself starts.

Among the variety of anti-virus software, it is worth noting specially disk utilities that start directly from an optical media or USB device, have their own boot records and even a graphical interface like Windows. One of the most powerful tools is Kaspersky Rescue Disk. Its use can guarantee almost one hundred percent detection of viruses, even those hiding in RAM.

RAM conflicts

Now let's see what to do if the computer does not boot and instead a blue screen appears. As already mentioned, most often this indicates problems with drivers and RAM. We’re not touching the drivers yet, but let’s look at the RAM.

The proposed solution to the issue of if the computer does not boot is mainly designed for stationary PCs. In this situation, you should remove all memory sticks, and then insert them one by one and check the load. Perhaps one of them is the link that causes failures. This may occur when trims from different manufacturers are added.

If the system can somehow be loaded using the same safe mode, the RAM should immediately be checked using the Memtest86+ utility, which will help identify the true cause of the problem.

The system does not see the hard drive

Now the worst situation is when the computer does not boot. The causes and solutions may be related to the hard drive.

A hard drive can have both software and physical problems, although sometimes that’s not even the issue. The problem may be completely trivial: the user in the BIOS settings has set the priority for booting from a removable device, for example, from an optical disk, which is currently in the drive, but is not a system one. You just need to remove it and download again.

On the other hand, another problem that the computer does not start (the system does not start) may be due to the fact that the bootloader and the records of the corresponding sector are damaged. The solution to this situation will be discussed a little later. But in the simplest case, you can try to restore disk data using Recovery utilities.

Sometimes changing the settings of the primary BIOS input/output system also helps. Here you need to find the section related to setting up the hard drive, and in the SATA configuration parameters, deactivate the use of AHCI mode.

Finally, the hard drive may also have purely physical damage, and this cannot be done without outside intervention.

Using the installation disc

Many users clearly underestimate the help that an installation or boot disk with a system image can provide in solving problems associated with situations when the computer turns on, but the operating system does not boot.

Firstly, almost any kit includes a so-called recovery console, with which you can eliminate many software failures, and secondly, you can use the command line here. This, by the way, is the most effective method. Next it will be clear how this works.

Problems with the BOOTMGR bootloader

It is believed that the most common problem when the computer turns on, but the operating system does not start, is damage to the windows loader (Boot Manager). In this case, the system just writes that there is no system partition (it simply does not see the hard drive).

You can fix this problem by starting from the boot disk and going to the command line in the recovery console, to open which you press the “R” key. Next, you need to first use the check disk command and then fix (restore) boot records.

The whole sequence looks like this:

chkdsk c: /f /r;
Bootrec.exe /FixMbr;
Bootrec.exe /FixBoot.

After entering commands, punctuation marks are not placed, but the enter key is pressed. If for some reason executing these commands does not have a positive effect, you can alternatively use a complete rewrite of the boot sector, which is performed by the Bootrec.exe / RebuildBcd command. If the hard drive is not physically damaged, this should work, as they say, one hundred percent.

You can also use some third-party utilities. The most suitable program seems to be a tool called MbrFix, which is included in the Hiren’s Boot CD. After calling it, for example, for Windows 7, provided that this particular system is installed, and only on one disk (there is no partitioning), you should write the following:

MbrFix.exe /drive 0 fixmbr /win7.

This will save the user from having to make changes to boot records, and the boot will be restored.

Problems accessing the NTLDR file

When a message appears that a given component is missing from the system, a boot commit is first applied, as in the previous case.

However, if the result is not achieved, you will need to copy the original file to the root of the system partition. For example, if the drive is "C" and the drive is "E", the command would look like this:

E:\i386> copy ntldr C:\ (after copying, the system will boot without problems).

Damaged or missing HAL.dll file

If the computer turns on, but the operating system does not load in normal mode, the reason may be a damaged component HAL.dll (a corresponding notification may be displayed on the screen).

In this situation, you need to boot the system in safe mode, call the command console and write the following line in it:

C:\windows\system32\restore\rstrui.exe (then press the Enter key and restart).

Instead of a total

Here is a brief summary of everything that concerns solving the problem of the inability to start the operating system. Naturally, the issues that the cause could be low power, CMOS battery failure, loose cable connections, dust inside the system unit, or other malfunctions were not addressed here. But in software terms, the above methods work flawlessly.

What to do if your computer won't boot

The first step is to establish the cause of the malfunction. If the situation is such that the computer turns on, but then the operating system (OS) itself does not load, then naturally you need to dig towards the same OS.

And if the situation is that the computer does not even turn on at all, that is, it shows absolutely no signs of life, then the situation can be much worse.

A few recommendations on what to do if your computer won’t boot!

For the first case (when the computer turns on, but the OS itself does not boot).

Here, as a rule, there is a problem with system files, either they are damaged or completely lost. Try using the tips below, all tips are given for Windows XP:

Use the “Load last known known configuration (with working parameters)” option. You can use it as follows: after turning on the computer, press the F8 key, a window will appear, and in it select the above-mentioned menu item.
Enter safe mode and try to restore the computer to its previous state. To do this, when booting the computer, press the F8 key (as in the previous paragraph), select “Safe Mode”, if the system boots, go to the following path: Start -> All Programs -> Accessories -> System Tools -> System Restore. And following the wizard's prompts, try to restore an earlier working system.
If the previous methods did not help, then I suggest you familiarize yourself with another option. This option will return your computer to working order with a 99% probability. What do we have to do? You just need to update the old system. To do this, you will need a boot disk with Windows XP. Insert the disc into the DVD-ROM, reboot, it should boot from the CD, for this you need to set the appropriate item in the BIOS, or you can call up the boot option menu with the F12 key when booting the PC and select boot from CD/DVD-ROM, but This method may not be suitable for everyone. After booting from the CD, select “Install windows XP” following the prompts. When a window appears notifying you that a previously installed OS has been found, press the R key. This way, the Windows installer will update the existing copy. Wait until it finishes and try to boot normally.

For the second case (when the computer does not turn on at all).

In fact, there can be a lot of reasons for this, and it can sometimes be very difficult to help in absentia in this case. And, as a rule, the reason is a malfunction of some device (motherboard, power supply, RAM, etc.). At home, especially for an inexperienced user, there is simply no way to check the functionality of a device by replacing it with a known working one. But there is a way out, although not 100%.

First, try resetting the BIOS. To do this, you need to remove the battery for a few minutes. Or close the jumper contacts to reset the BIOS. Look for a jumper next to the battery labeled Clear CMOS (possible designations: CCMOS, CL_CMOS, Clear RTC, CRTC, CLRTC, CL_RTC). If it doesn't help, read on.

Second. It is necessary to disconnect ALL devices on the computer, leaving only the motherboard connected. That is, we take out the video card, all RAM slots, disconnect the hard drive and DVD-ROM from the power supply, if there are additional devices (internal modem, sound card, etc.) we take them out, leaving only the motherboard connected to the power supply.

And now we try to turn on the computer, if it turns on, then the problem is in one of the disabled devices. Turn off the computer and try to connect the devices ALTERNATELY, checking the computer for functionality. First, connect the most important devices (video card, hard drive, RAM), and then the secondary ones.

And if the situation is that the computer does not even turn on at all, that is, it shows absolutely no signs of life, then the situation can be much worse.

A few recommendations on what to do if your computer won’t boot! Here, as a rule, there is a problem with system files, either they are damaged or completely lost. Try the tips below, all tips are given for Windows XP.

The first case (the computer turns on, but the OS itself does not boot).

1) Use the “Load last known known configuration (with working parameters)” option. You can use it as follows: after turning on the computer, press the F8 key, a window will appear, and in it select the above-mentioned menu item.

2) Enter safe mode and try to restore the computer to its previous state. To do this, when booting the computer, press the F8 key (as in the previous paragraph), select “Safe Mode”.

If the system boots, go to the following path: Start -> All Programs -> Accessories -> System Tools -> System Restore. And following the wizard's prompts, try to restore an earlier working system.

3) If the previous methods did not help, then I suggest you familiarize yourself with another option. This option will return your computer to working order with a 99% probability. What do we have to do? You just need to update the old system.

To do this, you will need a boot disk with Windows XP. Insert the disc into the DVD-ROM, reboot, it should boot from the CD, for this you need to set the appropriate item in the BIOS, or you can call up the boot option menu with the F12 key when booting the PC and select boot from CD/DVD-ROM, but This method may not be suitable for everyone.

After booting from the CD, select "Install Windows XP" following the prompts. When a window appears notifying you that a previously installed OS has been found, press the R key. This way, the Windows installer will update the existing copy.

Wait until it finishes and try to boot normally.

The second case (the computer does not turn on at all).

At home, especially for an inexperienced user, there is simply no way to check the functionality of a device by replacing it with a known working one. But there is a way out, although not 100%.

First . Try resetting the BIOS. To do this, you need to remove the battery for a few minutes. Or close the jumper contacts to reset the BIOS. Look for a jumper next to the battery labeled Clear CMOS (possible designations: CCMOS, CL_CMOS, Clear RTC, CRTC, CLRTC, CL_RTC). If it doesn't help, read on.

Thus, if, when installing a device, the computer stops turning on, you can independently determine the faulty device. If the computer does not turn on with one motherboard, then the problem is either with the motherboard itself or with the power supply.

There are many reasons why Windows 10 (7, 8, XP) does not load. Often in this case, an unpleasant situation is accompanied by a specific error message. But what to do if Windows 10 (7, 8, XP) does not boot on a laptop or regular PC without such messages? There are several universal treatment methods that can lead to a way out of this situation.

Selecting the download type

This is the simplest fix method if Windows 7 or another type of operating system from Microsoft does not load. What you need to do:

Start rebooting the computer.
Press the “F8” button.
In the proposed list, select the launch item with the most successful configuration.

In some cases, this action is quite sufficient when Windows 7 (8, 10, XP) does not load.

Windows Recovery

So Windows won't boot. You can try to return Windows to full functionality using the recovery menu. To do this, of course, you will need to have a boot disk with the desired OS option on hand. What actions should the user take in this case if Windows 7, 8, 10 and XP does not load:

Insert the source into the drive.
Change the priority in BIOS. That is, the operating system should not be launched from a hard drive, but from a DVD-ROM.
After starting the process, you will need to press the “R” button.
Select the option to restore.
Wait for the results. Restart the equipment one more time.
Windows XP (7, 8, 10) still won't load early? Next option.

Recovery within the OS itself

If previous operations have been carried out, but Windows 7 still does not boot, you can try to restore it directly using the tools of the operating system itself. It's quite simple:

Pressing the magic button “F8”.

Selecting further boot in security mode.

Obtaining limited access to the operating system.

Making the transition: “Start” – “Standard” – “Service” – “Recovery”.

An attempt to return the OS to an earlier state that was stable.

Naturally, at the end you will need to restart the computer to check whether Windows 10 (7.8, XP) does not boot or whether the problem has been successfully resolved?

Boot file disinfection

If Windows 7 does not boot after updating, then the possible cause of the problem lies in a damaged Boot.ini boot file. To fix the problem you will need to follow these steps:

Start the PC using the same external source.
In the recovery menu, go to the command line.
Enter the phrase “Bootcfg/add”.

Wait for the process to complete and initiate another reboot to check whether Windows 8 or its equivalent of a different version does not boot, or whether the treatment helped in this predicament?

Boot record defect

Perhaps this action will be quite enough when Windows 7 does not load and freezes on the logo.

Damage to the boot sector on the hard drive

Quick reinstall

What is required from a person:

Start again from the boot disk.
Press the “R” button, then the “Esc” key.
Select quick reinstallation of the operating system.

It is important to understand that this procedure can only work if identical versions of the OS are located on the disk and hard drives. That is, if, for example, Windows 10 does not boot after the update, you should not try to quickly reinstall it using a boot disk with Windows 7 or 8 for this purpose.

Conclusion

Unfortunately, sometimes you can encounter quite serious problems with turning on computers and starting operating systems, although until a certain point there were no signs of trouble. It happens that most often the computer turns on, but the operating system does not start. It is these situations that will be discussed further. Let's look at questions related to why the computer won't boot and what to do in such situations. There are several universal solutions here.

The computer turns on, but the operating system does not start: reasons

Among all the possible situations when failures occur at the loading stage, several typical cases can be identified.

There are three options:

a black screen appears;
Blue screen BSoD occurs;
The operating system starts, but cannot fully boot.

The computer turns on but does not boot: what to do first?

So, let's start with the simplest thing. Let's assume that a short-term technical failure has occurred in the system, for example due to incorrect shutdown or power surges.

As a rule, almost all Windows modifications used today usually automatically activate startup upon restart. If this does not happen, before starting the system you will have to use the F8 key to call up the additional boot menu (Windows 10 uses a different method).

Possible viral infection

Unfortunately, viruses can also cause such situations. What to do if the computer does not turn on? Ways to solve this particular problem boil down to using a powerful one that could check for threats even before the OS itself starts.

RAM conflicts

If the system can somehow be loaded using the same safe mode, the RAM should immediately be checked using the Memtest86+ utility, which will help identify the true cause of the problem.

The system does not see the hard drive

Now the worst situation is when the computer does not boot. The causes and solutions may be related to the hard drive.

Finally, the hard drive may also have purely physical damage, and this cannot be done without outside intervention.

Using the installation disc

Many users clearly underestimate the help that the installation or system image can provide in solving problems associated with situations when the computer turns on, but the operating system does not load.

Problems with the BOOTMGR bootloader

It is believed that the most common problem when the computer turns on, but the operating system does not start, is damage to the Windows boot manager (Boot Manager). In this case, the system just writes that there is no system partition (it simply does not see the hard drive).

The whole sequence looks like this:

chkdsk c: /f /r;
Bootrec.exe /FixMbr;
Bootrec.exe /FixBoot.

MbrFix.exe /drive 0 fixmbr /win7.

This will save the user from having to make changes to boot records, and the boot will be restored.

Problems accessing the NTLDR file

When a message appears that a given component is missing from the system, a boot commit is first applied, as in the previous case.

E:\i386> copy ntldr C:\ (after copying, the system will boot without problems).

Damaged or missing HAL.dll file

If the computer turns on, but the operating system does not load in normal mode, the reason may be a damaged component HAL.dll (a corresponding notification may be displayed on the screen).

In this situation, you need to boot the system in safe mode, call the command console and write the following line in it:

C:\windows\system32\restore\rstrui.exe (then press the Enter key and restart).
