Most of the opportunities that the average owner of desktop computers and laptops uses are available to humans through the use of special operating systems on the equipment. The most popular operating system is a product from Microsoft. Therefore, if Windows 7 or one of the other OS options does not boot, the user has serious problems.
There are a lot of reasons why Windows 10 (7, 8, XP) does not boot. Often in this case, an unpleasant situation is accompanied by a message about a specific error. But what to do if Windows 10 (7, 8, XP) does not boot on a laptop or a regular PC without such messages? There are several universal methods of treatment that can lead to a way out of this situation.
Selecting the type of download
This is the easiest fix if Windows 7 or another type of operating system from Microsoft does not boot. What will need to be done:
- Start restarting your computer.
- Press the "F8" button.
- In the proposed list, select the launch point with the most successful configuration.
In some cases, this action is quite enough when Windows 7 (8, 10, XP) does not load.
Windows recovery
So, Windows won't boot. Windows can be tried to return to full functioning 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 perform in this case if Windows 7, 8, 10 and XP does not boot:
- Insert the source into the drive.
- Change the priority in BIOS. That is, the operating system should not run from the hard drive, but from the DVD-ROM.
- After starting the process, you will need to press the "R" button.
- Select the variant to restore.
- Wait for results. Restart the machine one more time.
Everything early does not boot Windows XP (7, 8, 10)? Next option.
Recovery in the OS itself
If the previous operations were carried out, and Windows 7 does not boot anyway, you can try to restore it directly using the tools of the operating system itself. Everything is quite simple:
Naturally, at the end, you will need to restart the computer to check - Windows 10 (7.8, XP) does not load or has the problem been resolved with a positive outcome?
boot file treatment
If after updating Windows 7 does not boot, then the possible cause of the trouble lies in the corrupted 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 if Windows 8 or its equivalent of another version does not boot, or did the treatment help in this predicament?
Boot record defect
Another variant of trouble with Windows. Windows not loading? The boot record may have been corrupted. In this situation, you will need to repeat almost completely the 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 boot, hangs 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 further than "Welcome". Here, the treatment is also quite simple - the actions are repeated with the launch of the line for commands from the computer user, into which you should drive in “Fixboot” and then the letter that is responsible for the hard disk partition where the installed OS version is located.
Quick reinstall
Sometimes, if the computer does not boot past the Windows 7 splash screen, only a reinstallation can help. But it is not at all necessary to launch a full-fledged procedure that lasts long enough. You can speed up this process. It is a very powerful treatment tool, as it is able to cope with most of the troubles that have arisen.
What is required from a person:
- Run again from the boot disk.
- Press the "R" button, then the "Esc" key.
- Choose a 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 on the hard drives. That is, if, for example, Windows 10 does not boot after the update, but you should not try to quickly reinstall using a boot disk with Windows 7 or 8 for this purpose.
Conclusion
A special case of such a situation can be a constant automatic reboot of the OS. Naturally, this option excludes the possibility of any medical 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 Options" menu. After that, disable the OS reboot procedure and when 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, where a specific error code is indicated. And each of them has its own method of correcting an unpleasant situation. Most of them can be easily found on this Internet resource dedicated to answers to questions related to OS damage from Microsoft.
A frequent question of computer users is why Windows 7 does not start or does not start. At the same time, quite often there is no additional information in the question.
Therefore, I thought it would be a good idea to write an article that will describe the most common reasons why you might have problems starting Windows 7, the errors that the OS writes, and, of course, ways to fix them.
It may turn out that none of the options suits you - in this case, leave a comment on the article with your question, and I will try to answer as soon as possible. I note right away that I do not always have the opportunity to immediately give answers.
Disk boot failure, insert system disk and press Enter
One of the most common mistakes: after turning on the computer, instead of loading Windows, you see an error message: Disk Boot Failure.
This suggests that the disk from which the system tried to start, in its opinion, is not a system disk. This can be caused by various reasons, the most common of which (after describing the reason, a solution is immediately given):
1) A disc is inserted into the DVD-ROM, or you connected a USB flash drive to the computer, while the BIOS is configured in such a way that it sets this drive as the default boot drive - as a result, Windows does not start.
Try disconnecting all external drives (including memory cards, phones and cameras charged from the computer) and pulling out the drives, then try turning on the computer again - it is likely that Windows 7 will start normally.
2) The BIOS has an incorrect boot order - in this case, even if the recommendations from the method above were followed, this may not help.
At the same time, I note that if, for example, Windows 7 started up this morning, but now it doesn’t, then you should still check this option: BIOS settings can go wrong due to a dead battery on the motherboard, due to power failures and from static discharges . When checking the settings, make sure the system hard drive is detected in the BIOS.
3) Also, provided that the system sees the hard drive, you can use the Windows 7 startup repair tool, which will be discussed in the very last section of this article.
4) If the hard drive is not detected by the operating system - try, if possible, disconnecting it and reconnecting it, checking all connections between it and the motherboard.
There may be other reasons for this error - for example, problems with the hard drive itself, viruses, etc. In any case, I recommend trying everything that is described above, and if this does not help, go to the last part of this guide, which describes another method that is applicable in almost all cases when Windows 7 does not want to start.
BOOTMGR is missing error
Another error due to which you cannot start Windows 7 is the message BOOTMGR is missing on a black screen.
This problem can be caused by a variety of reasons, including the operation of viruses, independent erroneous actions that change the boot record of the hard drive, or even physical problems on the HDD.
NTLDR is missing error. Press Ctrl + Alt + Del to restart
In its manifestations and even in the method of solving this error, it is somewhat similar to the previous one.
In order to remove this message and resume the normal start of Windows 7, use the previous instructions.
Windows 7 starts but only shows black screen and mouse pointer
If, after starting Windows 7, the desktop does not load, the start menu, and all you see is just a black screen and a cursor, then this situation is also quite easy to fix.
As a rule, it occurs after an independent or with the help of an antivirus virus removal program, when, at the same time, the malicious actions committed by it were not fully corrected.
Fixing Windows 7 startup errors with built-in utilities
Often, if Windows 7 does not start due to hardware configuration changes, improper shutdown of the computer, and other errors, when you start the computer, you may see a Windows recovery screen where you can try to restore Windows startup.
But, even if this does not happen, if you press F8 immediately after loading the BIOS, but even before Windows 8 starts loading, you will see a menu in which you can launch the "Troubleshoot your computer" item.
You will see a message stating that Windows files are being downloaded, and after that - an offer to select a language, you can leave Russian.
The next step is to log in with your account. It is better to use the Windows 7 Administrator account. If you did not set a password, then leave the field blank.
After that, you will be taken to the system recovery window, where you can start an automatic search and fix problems that prevent Windows from starting by clicking on the appropriate link.
After searching for problems, the utility can automatically fix errors that make Windows not want to start, or it can report that no problems were found.
In this case, you can use the system restore functions if the operating system has stopped starting after installing any updates, drivers or something else - this can help. System Restore, in general, is intuitive and can help you quickly solve the problem with starting Windows.
That's all. If you have not found a solution to your particular situation with the launch of the OS, if possible, describe in detail what exactly is happening, what preceded the error, what actions have already been tried, but did not help.
Good time everyone!
Despite the fact that each new version of Windows is becoming more stable and reliable, all the same, unpleasant incidents often happen to it...
For example, a seemingly banal thing, a power outage and a crash can easily lead to the fact that after turning on the computer - Windows will no longer boot (moreover, this also applies to the newfangled Windows 8.1, 10)! Although, of course, there are many more reasons for this misfortune.
Actually, in this article I want to analyze in more detail what can be done to restore windows boot(or at least minimize your losses).
By the way, it is worth immediately clarifying one moment:
So, now on to the topic...
The first thing I would advise you to do is pay attention to the screen. Often you can see an error message on it, its code, description (and knowing this information, it will be easier to find and diagnose the cause).
For example, the photo below shows one of the typical errors "Disk boot failure ..." (an error associated with bootable media, by its solution, I have). I note that in your case the error may be somewhat different (there are quite a few of them).
In general, all the popular errors that can be seen at the stage of loading a computer have long been sorted out by many specialists (including on the official Microsoft website).
In general, the message of the first step is simple.: if you get a specific error - write it down and try to find a guide to solve this particular problem. The situation is worse when there are no errors at all and it is not clear what to do next ...
⇒ By the way!
If after turning on the PC / laptop you just have a black screen (i.e. there is no image on it) - I recommend that you read this instruction:
STEP 2: disconnect all "extra" hardware from the computer
The next thing to advise is to disconnect all unnecessary equipment from the laptop / computer: a second monitor, printers, mice, speakers, headphones, etc. Particular attention to flash drives, CD / DVD drives, SD cards, and other drives.
The fact is that with certain BIOS settings, the computer can "search" for boot records on the same flash drive, and not finding them, simply do not proceed to boot Windows from the hard drive.
Note: after you turn off all the "extra" - restart your computer.
STEP 3: check BIOS settings
If you changed the BIOS settings (or reset them, for example) or connected another hard drive to the PC, then it may happen that incorrect settings will be indicated in the BOOT (boot) section (for example, the wrong boot device may be selected).
As an example, below is a photo of the BOOT section. Pay attention to the sequence: 1st is the CD / DVD drive, 2nd is the hard drive. In some cases, the PC may "refuse" to boot Windows from the hard drive (in this order).
Need: put the hard drive in first place, save the settings (usually the F10 key) and restart the PC.
⇒ Help! By the way, you can simply reset the BIOS settings to factory settings (as a rule, they are universal and by going to them you can solve most problems) -
STEP 4: try repairing the Windows bootloader

STEP 5: run your PC for viruses
Some viruses can corrupt system files, delete information from the hard drive, block some functions and features of the OS. All this can lead to a wide variety of problems with Windows, including the one discussed in this article. (Moreover, restoring in the previous step can help exactly until the next reboot).
In order to drive your disk from the OS to viruses (when Windows itself does not boot), you can resort to two ways:
- take out the hard drive from a computer / laptop and connect it to another device on which a modern antivirus with updated databases is installed ();
- create a live cd flash drive (i.e. from which you can boot even if your PC does not have a hard drive) and run HDD check from it. Now such images for writing to a USB flash drive can be downloaded from the official sites of antiviruses.

Often, many users wait for Windows to load for 5-10 minutes (some of them, by the way, believe that it is frozen and are in a hurry to restart the PC again and wait for this time again).
In general, the first thing I would advise you to do in this case is check autoload(the more programs it contains, the longer it will take to load the OS). Pay special attention to all sorts of torrent programs: if you have hundreds of torrents in them, downloading can become very long!
In Windows 10, to see the autoload, just open the task manager (shortcut Ctrl + Shift + Esc). You can also use various special utilities such as .
In addition, check Windows with some utility to clean up junk, temporary files, fix registry errors, etc. All this in a compartment can also seriously affect the speed of the OS.
I have a separate article on my blog dedicated to the best utilities for maintaining and cleaning Windows. -

STEP 7: how can you copy your data from the disk if Windows still won't boot
If all the previous recommendations have not been successful, then before formatting and reinstalling Windows (or some other more drastic measures), it is advisable to make a copy of all important documents from the hard drive. You never know ... suddenly something goes wrong? ..
Method 1
The easiest way is to remove the hard drive, connect it to another computer and transfer all important data from it. By the way, now on sale you can easily find various "boxes" for connecting an HDD to a regular USB port (it greatly facilitates the work).
Method 2
That's all for now...
For additions - a separate merci!
We will fix errors in Windows 10. But we will have to do about the same in Windows XP, 7 and 8. In Windows 7 and later, developers have improved the recovery system after startup problems. In older versions of the system, serious errors often have to be solved by reinstallation.
Disable Peripherals
Try to remember what changes you recently made to the system: whether you installed new devices, devices, or switched something. Perhaps the problem is in one of the hardware components. Try to disable:
- USB drives.
- Card readers.
- Printers.
- Scanners.
- Cameras.
- All other external devices.
If this does not help, disconnect the keyboard and mouse: you need to eliminate all possible sources of the problem.
Internal components such as RAM can also be the cause. In a desktop PC, you can check the performance of the RAM by connecting the brackets one by one.
Check nutrition
If the computer does not turn on at all, pay attention to the power cable and sockets. Don't forget the power switch on the back of the desktop case.
If everything works at this level, but the computer still does not turn on, then most likely the problem is in the power supply, which you are unlikely to be able to fix yourself: you will have to replace or repair it by a specialist.
It is possible that the computer turns on, but only for a short time. It's the same problem with the power supply.
Set up a disk to boot the system
Errors may appear during startup: An operating system wasn't found. Try disconnecting any drives that don't contain an operating system. Press Ctrl+Alt+Del to restart or boot failure. Reboot and Select Proper Boot device or Insert Boot Media in selected Boot device.
The BIOS or UEFI settings may be set to boot from an external device or other logical partition, and not from the system drive. You can restore the default settings like this:
- To restart a computer.
- Immediately after the restart, press the system key, for example F2. This may be another key: usually during system boot, it can be found at the bottom of the screen with the logo of the manufacturer of the laptop or motherboard.
- In the settings, set the desired disk to the first place in the boot.
- Select the Save and Exit option to save your changes.
If the above did not help, you will have to restore the system bootloader. To do this, you will need a bootable USB flash drive or recovery disk with a system that is suitable in terms of bit depth. How to make a bootable USB flash drive or disk, read Lifehacker about installing Windows.
Start the system from a USB flash drive or disk by selecting the desired option in the boot menu. In the Windows installation menu that opens, select System Restore.
From the recovery menu, select Troubleshooting → Advanced Options → Startup Repair. After that, the system will try to automatically fix the bootloader. In most cases, it solves the problem.
The same can be done manually through the command line, but it is better to choose the automatic option so as not to aggravate the situation.
If this method did not help, the problem is probably in the hardware: the hard drive is damaged.
From the recovery menu, select Troubleshoot → Advanced Options → Command Prompt.
At the command line, you need to enter the commands one by one: diskpart → list volume (be sure to remember the name of the disk with Windows) → exit.
To check the drive for errors and corruption, type chkdsk X: /r (where X is the name of the Windows drive). The check usually takes a long time, you have to wait.
Start Windows in Safe Mode
Due to a sudden shutdown of the computer during the installation of operating system updates, cleaning of viruses and unnecessary entries in the registry, or through the fault of utilities to speed up Windows, system files may be damaged. In this case, the blue screen of death will appear when the system boots.
Try to start Windows in safe mode without loading drivers and programs in autorun. If the computer works in this mode, you will have to remove the drivers, perform a system rollback and scan for viruses.
If you have restore points, this problem is quite easy to solve. You just need to roll back to the previous stable configuration.
Reinstall system files
The steps above may not help. Then you have to reset Windows settings and reinstall the system while saving the files. Unfortunately, all programs will need to be installed again.
In the recovery environment, select Troubleshoot → Reset this PC → Keep my files → Reset.
The system will roll back to the original settings.
Good health to all, my dear readers, blog guests, as well as novice system administrators and programmers.
Black screen
A very common and common occurrence when, after rebooting and installing updates, you see only a black screen. No inscriptions, no drawings, sometimes even without a cursor. This happens due to the fact that new files relating to the operating system itself have been introduced into the system. Either the data package was crookedly installed or downloaded.
Especially often this can be found when, during the installation of the system, the user simply turns off the power or restarts the computer on his own.
A black screen indicates that the system is interrupting its loading at the stage of entering the graphical shell. It is treated by rolling back the system to the last successful working state.
Blue screen
The blue screen is a more serious problem, especially with white labels. This means that the system is "crashing". That is, its system files fail, due to which the shell itself completely fails.
The blue screen with error c0000145 is especially dangerous. In this case, I recommend completely reinstalling Windows, otherwise there is a great risk that one fine time you will simply lose all the files.
Also, it is worth checking your hard, it happens that when it gives errors, the OS starts to turn blue.
In such situations, I recommend taking the hard drive to a workshop for professional diagnostics. This is not the case when you see a black screen with a cursor, this is already a serious problem that needs to be addressed immediately. Rolling back updates and restoring the OS from an earlier one will not help here. It is necessary to completely demolish the shell and put a new one. Just don't forget to transfer the files.
Computer keeps restarting
Frequent problem. It is associated with broken files of the update packages themselves or occurs when the service pack is downloaded from an unconfirmed source. Sometimes crooked programmers disassemble the update on their own, throw out everything that, in their opinion, is superfluous from it, then archive it and distribute it on torrents.
After installing on a laptop, a problem appears, the machine constantly reboots. In such cases, you need to restore the operating system from an earlier state through a checkpoint. You can do this through safe mode or using a bootable USB flash drive (or disk). Also, this can happen when you download any software for the android system. Therefore, I recommend downloading such software directly to your smartphone.
How to uninstall an update?
Let's imagine that you installed a service pack, and it gives an error. In this case, the update must be demolished. This is done in the following way. From here download the seventh Windows.
A from here Ultra ISO program. Install the software and insert a clean USB flash drive into the USB port. We open the software.
We press the button open.
The program interface should display all the files that are on the image with the operating system.
Now, in the window that opens, in the first line, select our flash drive. In the second - we set the recording method the same as in the picture. Click record.
In the box that appears, click on " Yes” and wait for the end of the recording.
Now we need to boot from our flash drive. Not in safe mode, namely from a flash drive. We see such a screen, and click on this line.
In the window that appears, select the first position, click Further and wait for the end of the download.
Then select the operating system.
In the menu that appears, select the first line. The command line section could be useful to us if you knew how to work with it. But since I expected to write an article for inexperienced users, we will not touch it.
We press reboot and wait for the end of the operation. Everything, the update is rolled back, the system should work completely stably.
By the way, here's a helpful video.
Conclusion
Now you know what to do if you have a crooked update installed, how to fix errors in such a situation and not lose files.
Remember that all system data must be downloaded exclusively from the Microsoft website. This will at least protect you from such mistakes.
On this I will end the material. I hope it was useful for you, so share the link to it with your friends in social projects. Subscribe to my blog updates and stay up to date with new publications. See you soon, my dear readers and guests of the site!
