The stable operation of a computer or laptop the day before does not mean at all that the next launch will do without surprises. The most unpleasant and unexpected of them is that the OS does not boot. A blue or black screen with comments that are incomprehensible to the user makes you think about the worst, and frequent reboots are scary. In version 10, you can use automatic system restore or solve the problem manually. The first method can be used even by inexperienced users. Let's figure out what to do if Windows 10 does not start, why this happens and how to prevent it.
Distinguish between software and hardware startup failures. More often than not, problems occur due to the first type of error. There are several reasons:
- files from unverified sources. Virus-infected software products lead to damage to PC system components;
- the system has been updated. If the process went wrong or was interrupted by the user, then after updating and rebooting the PC will not boot;
- applications and programs are installed incorrectly;
- experiments with hard drive partitions: compression, partitioning, formatting, etc. At the next boot, a black screen will appear with "Bootmgr is compressed".
- disk cleaning using special software tools. When booting, a black screen will appear with "Bootmgr is missing";
- shutdown of the PC is performed incorrectly;
- there are dubious applications in the autorun. In this case, when the device is turned on, the system will start according to the standard, but at the last stage (before loading the desktop) it will reboot. The procedure may be repeated several times.
Why Software Glitches Cause Problems
Suppose, the day before, the user installed updates or drivers on a laptop or PC. Their download and installation was incorrect, that is, the files were not completely copied to the system disk. Therefore, the OS refers to the declared, but not installed drivers. Problems can also arise due to problems with RAM and as a result of changing bootable media in the BIOS. In the latter case, the computer looks for the required bootloader not on the system drive. A hardware failure also causes the OS to fail to boot.
The most “terrible” are the INACCESSIBLE_BOOT_DEVICE and CRITICAL_PROCESS_DIED errors, followed by the request to restart Your PC ran into a problem and needs to restart. These are the most common types of blue screen errors. In case of software and hardware failures, endless loading or rebooting can occur. In any case, you should not panic. You need to try to get into the OS recovery environment.
How to get into the recovery environment
Initially, Windows 10 will attempt to troubleshoot on its own, and if it fails to do so, it will display a blue screen to the user.
Often automatic recovery is successful. In this case, OS Windows 10 takes a long time to load, but as a result it starts up.
- Whatever blue window pops up, to solve the problem, you need to select the "Advanced Options" menu. Going to the menu will automatically transfer the user to the system recovery environment.
- At the next step, you need to select a "rollback" point - the date and time before updating the system, experimenting with disks, or downloading new programs.
Then click "Next" and "Finish". The process is completed by rebooting the PC. In 4 out of 10 cases, the actions taken will help. More severe cases (black screen, could not find the recovery environment) are solved by reinstalling Windows 10. A bootable flash drive (DVD) will also help.
In the latter case, the x32 Bit or x64 Bit OS distribution must already be written to external media. Every experienced user is sure to keep one at hand. It is called MSDart. When buying a licensed operating system, it is distributed free of charge.
You can also buy it on the official website or download it. The distribution kit contains the correct boot images of the operating system used.
Important! When recording a bootable USB flash drive or disk on your own, you need to clarify the bit depth of the installed system. It is for her and download MSDart. There are such errors that can only be fixed by reinstalling the OS or using a flash drive (disk) with MSDart.
How to restore the system from a bootable USB flash drive
To start the procedure, you need to insert the media into a PC or laptop. Then reboot the device by pressing F2 or F8 at the time of reboot. This action will take the user to the BIOS settings of the computer.
- Here you need to select the priority of the bootable media that was connected to the PC.
- Press exit. The last item will save the changes and reboot from the installed external media. After the reboot, the first window will appear on the screen, prompting you to select the download language.
Important! The principle of choice and the window for changing boot priorities depends on the motherboard.
- Click on the "Next" button and follow the steps shown in the picture below.
Here we need a menu item "System Restore". We pass to the new menu "Choice of action".
- We perform the transition to the list item "Troubleshooting". We get into the "Advanced Options" menu.
- The easiest way is to return to a given point - that is, to that set of drivers, system files, and other things that gave 100% and the correct loading of Windows 10. This opportunity is provided by the "System Restore" list item. You need to click on it. In a new window, put down the date and time of the "point" that you want to use to start.
The menu item cannot be used if control points have not been saved.
The second easiest option to restore the OS will be "System Image Recovery"
The method will only work if the images were saved. Since backup copies of the operating system are created only by advanced users, then, most likely, this menu item will not be able to be applied.
If you have a backup in the window that appears, just specify the location of its storage and click on "Next".
This command will cause all broken files to be automatically replaced with healthy copies from the archive.
If the user performed the installation of an additional OS, accidentally formatted, compressed and other manipulations with boot files, then you need to go to the "Recovery at boot" item. In that menu, the bootloader will be restored and Windows 10 will automatically start. The procedure will take a lot of time.
Users of the licensed version of the OS can use the item "Return to the previous assembly". When the system is properly updated, the old version files are saved to the Windows.OLD folder. This is temporary help. The performance of the system will be preserved for 10-30 days. When using this solution to the problem, you need to come to terms with the fact that files created after updating the OS will be lost.
Windows 10 boot problem may occur for a variety of reasons. One of them is damage to the standard bootloader Windows Boot Manager, which is responsible for the actual launch of the "dozens". This usually happens when several operating systems are installed on the computer and we unsuccessfully removed one of them. There are other reasons as well. In these cases, immediately after the start screen, instead of the Windows logo, an inscription about the impossibility of loading the OS appears (for example, “An operating system wasn’t found”) and a lot of other text in full screen on a black background.
If it's a boot sector corruption, then you can try automatically repair Windows 10 bootloader using media with an ISO image of the version of Windows 10 installed on the computer (flash drive or DVD). There are other ways (for example, through the command line, again when starting from a USB flash drive with an ISO image), but personally, in all cases, it was the simple option described below that helped me - so why look for complex paths where simple ones can work?
To automatically repair the Windows 10 bootloader, so that our operating system restarted, you need to boot from a flash drive. How exactly to do this, you need to look specifically for each computer. For example, when I start, I need to press F12, and then select a USB flash drive with a clean image of Windows 10 from the list and the computer will boot from it. You can set the flash drive as a priority boot device in the BIOS (or UEFI). if something is not clear, then on the Internet you can find boot options from removable media for your specific model of computer or laptop.
Automatic recovery of the bootloader using an ISO image of Windows 10 (from a USB flash drive, DVD)
After starting from a USB drive, after a while a screen will appear, as in the picture below. We click on it "Next", as about the usual clean installation of Windows 10.
But in the next step, we need to choose NOT “Install”, but “ System Restore».
Now select the following action: Troubleshooting».
In the next menu, go to " Extra options».
We select our operating system (it is not always suggested to do this - sometimes recovery starts bypassing this stage.)
As a rule, in the end, Windows 10 still starts as it should. And this indicates that the bootloader is restored.
If restore Windows 10 bootloader automatically If it doesn't work, then you should try to do it using the command line.
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 have been 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.
It is not uncommon for Windows 10 users to encounter a blue screen or black screen situation at system startup with an error message. Loading errors are very unpleasant for the user, especially since you won’t even be able to use the computer. Moreover, there is no information about the possible cause of the failure.
Please note that download errors appear due to both software and hardware. In our article, we will look at the main errors when loading Windows 10 that occur due to software and how to solve them.
To identify and resolve boot errors, you need to analyze the state of your computer before the crash. The system stopped starting:
- after updating the BIOS or drivers;
- in connection with updating or installing an anti-virus program;
- after adding computer devices;
- due to incorrect shutdown.
Paying attention to the above factors, you can most accurately install and fix the error when loading Windows 10.
Windows 10 crashes on boot
The most popular failure scenario is when Windows 10 does not start when you turn on the PC, and an error message window pops up on the monitor. Next comes a blue screen with a notification and two possible solutions.
Such an error indicates (but not always) that the system files were damaged due to their removal, installations and “demolition” of applications (especially anti-virus ones), the use of software products for cleaning the registry and PC.
The fix for this problem is to repair the registry and corrupted Windows 10 system files. You can do this like this:
After that, you need to reinstall Windows 10 while maintaining system files. However, programs after this action will not be saved.
Error code 0x000000f when booting Windows 10
Windows 10 system may not boot for various reasons. One of the system problems of your PC is the error code 0x000000f, which occurs after cleaning it from dust.
After cleaning the computer from dust accumulations, the user is faced with the fact that the PC gives him a black screen when turned on with a description of this error in English in the "Status" item.
After that, you can restart the system at least 100 times or carry out other actions with memory or the motherboard, but the error will repeat all the time. The reason for it lies in the spontaneous wallpaper syndrome in the BIOS settings, that is, the correct settings of the devices with which Windows 10 is loaded have “flew off”.
The algorithm of actions to eliminate this error is as follows:
After that, the PC will restart without error 0x000000f.
Error loading BOOT Windows 10
Often, when starting the Windows 10 system, users can observe a blue screen with a notification on the computer monitor "inaccessible boot device".
This inscription means that the system has a problem accessing the file partition responsible for the boot mode. The blue screen in this situation serves as a protective "shield" to save your data.
To fix this error, you need to know what caused it. The reasons can be very different - after resetting the system, changing the partition structure on the disk, connecting another hard drive, or after updating the BIOS.
Before you start fixing the error when loading BOOT Windows 10, it is recommended that you try to restart your computer in this way:
- disconnecting additional drives from the PC (including flash drives and memory cards);
- checking the system disk for boot priority in BIOS or UEF;
- you also need to make sure that hard drives and SSDs are connected correctly to power and SATA interfaces if you cleaned the PC from dust or connected something to it;
If the error appeared after installing updates or resetting Windows 10, then it can be fixed in this way:
- On the screen "The computer did not start correctly"(it appears when you are looking for information about the error) you need to select "Extra options".
- Next click "Troubleshooting", go to "Download Options" and press "Reload". After rebooting the PC, select item 4 by pressing the F4 key, then - Windows 10 Safe Mode.
- After booting into safe mode, the computer again needs to be restarted ( Start - Shutdown - Reboot).
If a disk error occurred when loading Windows 10 (it was damaged or the partition structure on it changed), then you need to boot into the recovery environment. If you do not have the opportunity to do this action from the computer itself, then you can use the installation drive to start the recovery environment (bootable flash drive or recovery disk).
Bug fix:
Windows 10 boot error occurs and PC restarts
The reason Windows 10 boots up with an error and the computer restarts on its own is a failed automatic boot fix. You can solve this problem only from the recovery environment from a boot disk or flash drive using the method described above. When you boot into the Windows Recovery Environment, follow the same troubleshooting procedure as in "The computer did not start correctly".
Consider the designation of Windows 10 error codes:
- Error 0xc0000225 during boot is a problem associated with boot sector damage (virus exposure, erroneous shutdown of the OS, mechanical shock).
- Error 0x00000e9 (I/O) when loading Windows 10. It means that a failure occurred when disconnecting or during the operation of a removable storage device, as well as a hardware malfunction (hard drive, floppy drive).
- Error code 0xc000021a Windows 10 is called STATUS_SYSTEM_PROCESS_TERMINATED at startup and occurs when the Windows Logon Process stops and ends unexpectedly. Also, this error may occur from damage to RAM or HDD, the effects of viruses and malware on files, an unexpected failure when installing programs or drivers on the device.
The user often encounters various errors when loading Windows 10, which can be solved on their own. The main thing is to figure it out in time and identify the causes of the system failure during boot.
Hi all! In the last article, we learned how. In today's article, we will learn how to enter Windows 10 Safe Mode if the system does not boot due to any errors.
Friends, what usually causes our operating system to stop loading? That's right, due to corrupted system files and critical drivers, but most often Windows does not boot due to programs and drivers installed by us that are not designed to work in our operating system. I'll explain a little more.
How to Enter Windows 10 Safe Mode if the Operating System Won't Boot
Recently, one person contacted me, he successfully updated his Windows 7 to Windows 10, but after the update, his video card and TV tuner drivers crashed. I updated the video card drivers for it, but with the TV tuner it turned out to be more and more difficult, only drivers for Windows 7 were posted on the official website of the device, there were not even drivers for Windows 8.1. In support, they told me that there are no 100% working drivers on Win 10 yet, but there are beta drivers and they suit who and who do not.
I downloaded and installed the drivers along with the software for the TV tuner without even creating a restore point just in case. The driver installed and asked for a reboot, after the reboot, a blue death (blue screen) appeared on the monitor, several reboots led to the same effect - the system boot ended with a blue screen.
What happened. The blue screen of death is a defensive reaction of Windows to incorrectly working code, that is, the system was automatically protected by a blue screen from a malfunctioning TV tuner driver. To remove the incorrect driver, I decided to use safe mode.
- Note: everything would be easier if I had before installing the driver.
We all know that safe mode is specially designed to fix various operating system malfunctions. In Safe Mode, Windows 10 starts with a minimal set of Microsoft-owned processes that you can trust. Therefore, we can use safe mode to remove incorrectly working drivers, or programs that led to Windows boot failure or its unstable operation.
All this is clear, but how to enter safe mode if Win 10 does not boot!?
In the initial system installation window, click keyboard shortcut Shift + F10.
A command prompt window will open, enter (suitable for any computers, including laptops with the UEFI interface enabled and the Secure Boot option, the command:
bcdedit /set (globalsettings) advancedoptions true
the command will make a change to the boot storage configuration (BCD) file.
Operation completed successfully.
We restart the computer, the Advanced Boot Options window will open.
Press key F4 or 4 to enter safe mode, you can also use other special modes used when troubleshooting Windows 10.
If you want to enter the operating system in the usual way, then press Enter on the keyboard.
Here we are in Windows 10 Safe Mode.
We remove the incorrect driver or program in the usual way.
Usually, drivers are installed into the operating system along with the software.
Open the Computer window and click Uninstall or change a program.
We find the name of the non-working, properly, software and click Remove.
If you installed the driver without an installer manually, uninstall it directly in the Device Manager - right-click on it and select Uninstall.
If you want to remove the appearance of the Advanced Boot Options window when loading, then boot from a bootable Windows 10 flash drive into the recovery environment, start the command prompt, enter the command:
bcdedit /deletevalue (globalsettings)advancedoptions
This command will undo previous changes to the boot storage configuration (BCD) file.
For insurance, before work, you can do.
