Windows 10 won't start after updating. Windows won't boot after installing updates

One of the problems that users have begun to encounter is that the computer does not work after updating Windows 10. And this does not happen rarely. So what is the problem: a bug of the developers or something else? Let's take a closer look.

Causes

After the update, the system may not start, or may freeze for a long time. There are three main reasons:

• viruses or malware;
• many background applications;
• conflict between drivers.

These are the most basic reasons. In fact, there may be much more.

Remedies

So, the problem is that after updating Windows 10 the system does not start and something needs to be done. I suggest considering several methods to troubleshoot the problem.

Rollback

The most faithful and reliable method- return operating system to its original state. By the way, this will also work if you see a black screen while loading Windows. The algorithm of actions is as follows:

1. 1. Restart your PC.
   2. During startup, quickly press F8 to get to the recovery menu.
   3. Select a section there "Diagnostics".
   4. Open section "Extra options".

1. 1. Select "System Restore".

1. Following the Restore Wizard's prompts, select a rollback point and return the system to the time it was in working condition.

This method does not work if you have the restore point creation feature disabled.

Resolving conflicts with drivers

If Windows 10 does not boot after updating, then the drivers may be to blame. A conflict has occurred and the system does not work. First you need to start in safe mode, and if everything is fine there, then the drivers are to blame. Windows 10 has made it more difficult to log into safe mode. We will use the method where needed boot disk or a flash drive, since the system doesn’t work for us:

1. Boot from the installation device.
2. In the Windows Setup window, click "Further".
3. Select System Restore.
4. Open "Troubleshooting".
5. Select "Command line".
6. Write the code: bcdedit /set (default) safeboot minimal .
7. Click Enter and restart the PC with a special button.
8. The system will boot into safe mode.

Now the most important thing. If everything is fine in the BR and the OS is operational, then there is a driver conflict.

You need to do the following:

1. 1. Click Win+R.
   2. Type: msconfig and click Enter.

1. and disable all third party applications.

1. 1. Then open the tab "Services". Check the box next to "Do not display Microsoft services".

1. Disable all third party services and click "Apply", but do not restart your PC.

Now call the command line, write: bcdedit /deletevalue (default) safeboot and reboot the computer.

If after a reboot the system starts working normally, does not freeze, etc., then the problem was in the services and drivers. Now do the same thing, but turn on different drivers and services one by one until you find the one with the problem. If it is a service, deactivate it, and if it is a driver, remove it and install it again.

Treatment of viruses

It is possible that Windows 10 does not start after updating due to viruses and malware:

1. Search the Internet and download the PC treatment utility Dr.Web Cureit to a flash drive.
2. Boot the system in safe mode. I explained how to do this in the previous section.
3. Run the utility and conduct a full scan.
4. Remove all detected threats and start your PC in normal mode.

Conclusion

Here are some really working methods for solving the problem. Try them and if it helps, write in the comments.

Many users experience some malfunctions and malfunctions in their computer device after updating Windows 10. The main ones are the following:

1. Windows 10 does not boot for a long time.
2. The system does not want to start and work.
3. Black screen.
4. Appearance blue screen with mistakes.

To eliminate them, it is necessary to understand the sources of operational failures and possible ways getting rid of these sources.

If the system does not start after the latest Windows 10 update, remember how it behaved before shutting down or rebooting. Perhaps some program was loaded, or an error appeared after connecting a new device and a virus software. In the course of troubleshooting such problems, the system may improve or deteriorate its performance. Therefore, it is necessary to be prepared to restore it and return it to its original, working condition.

The system does not start or takes a very long time to load

The system takes a long time to boot or does not boot at all - this problem occurs at startup large quantity additional programs or malicious software connecting to the process. Therefore, you immediately need to check your computer for viruses and prepare electronic media with installation Windows files 10.

To solve the problem, take the following steps:

1. Using the media, we boot the device in safe mode. In the menu, select the source from which the system modules and drivers needed for your computer will be loaded.
2. Open Task Manager. This can be done using Ctrl keys+ Shift + Esc. Find the Startup tab.
3. Startup contains the entire list of applications that can be loaded when the system starts. It is necessary to select from among them the minimum that is needed for normal operation of the computer, and disable the rest.

These simple steps will help reduce system boot time and improve system startup.

Working with safe mode is useful when removing viruses, unnecessary programs, fixing driver errors, and activating an administrator account.

In addition, you can optimize and defragment the disk:

1. Click on Start.
2. Select the Computer tab, drive C.
3. In the window that opens, find the Properties item and click the Optimize button.

Taking advantage CCleaner program, you can remove all junk files from the disk and erroneous keys from the registry.

If Windows 10 does not work after updating, restore the system to an earlier working state. This method is only suitable if the computer creates system rollback points or restore points. To do this, you need to carry out the following procedure:

1. Reboot your system. Once it turns on, press F8.
2. The recovery menu appears.
3. Go to Diagnostics, then Advanced Settings.
4. Find the Recovery tab.
5. Following the instructions, select a Restore point to a rollback state from the available list.
6. Restart your computer. The current version of the operating system is removed.

Blue screen appears

CRITICAL_PROCESS_DIED. The error code is accompanied by the warning “The computer is not started correctly” or “ Windows system loaded incorrectly."

In such cases, a regular reboot helps.

INACCESSIBLE_BOOT_DEVICE. The error may appear after updating to Windows 10 or BIOS motherboard, when restarting the computer after a system rollback, partitioning of the hard drive, if files are damaged.

The easiest way to resolve this error is:

1. In the window Automatic recovery select More options.
2. Among the list of parameters, you need to find Boot options - Restart.
3. After the system restarts, press the F6 button to reboot into Safe Mode using the Command Prompt.
4. Enter the command phrases one by one:
   • sfc /scannow;
   • dism /Online /Cleanup-Image /RestoreHealth;
   • shutdown-r.

System files will be scanned and restored if they were damaged.

Black screen appears

There are malfunctions in which the computer device does not turn on, and the screen is black after the update. This problem occurs when video card drivers are installed incorrectly, exiting sleep mode, removing a virus, or downloading updates.

The screen can have 2 types:

1. With a mouse cursor.
2. No cursor, solid black display.

In the first case, the screen can have not only a mouse cursor, but also a rotating wheel. What does this mean and what to do in such cases?

Software glitch

This happens when the system booted only for the first time before Windows 10, when you turned off and immediately turned on or rebooted the computer. Software glitch occurs as a result of an update.

To restore the system, you need to update it again.

System conflict with primary drivers

Previously installed drivers may create a conflict with the system, so to resolve this issue, do the following:

1. Find Start - Control Panel. Under Power Options, click System Settings.
2. Under Shutdown Options, uncheck the Enable fast startup (recommended) box.
3. Save your settings.
4. Click on Start. Find the Computer tab.
5. Right-click Properties and do the following: Hardware - Device Manager - Video Adapters.
6. Find your video card and Update drivers. Drivers are installed either in automatic mode from the Internet, or from special software.

In the second case, when the screen is only black without a cursor, start the system in safe mode:

1. Press and hold on your keyboard Shift key, continuously click on the F8 button to open Safe Mode. This system launch is simple, but does not always work.
2. In the window that opens, find the following sections: Diagnostics - Additional parameters - Command line.
3. Type bcdedit /set (globalsettings) advancedoptions true.
4. Click the Enter button.
5. In the newly opened window, click Continue. The download continues.
6. In the new window, select Enable Safe Mode.
7. Press Enter.

Correcting virus activity

If the computer does not boot, the screen is solid and black, then most likely the system has been damaged by malicious virus software. Try the simplest method.

Boot Windows 10 in safe mode, scan with an antivirus application and delete infected files.

If viruses have damaged the explorer.exe file, which is responsible for the work GUI, you can perform the following operation:

1. Press Ctrl+Alt+Del keys simultaneously or open the Start menu.
2. Go to Task Manager, then Run new task.
3. Write explorer.exe in the line and run the task.
4. Through the Run line, pressing the Win + R buttons, enter the regedit command.
5. Expand the HKLM branch.
6. Go to the Software section.
7. Next, click individually Microsoft tabs- Windows NT - Current Version.
8. Open the Winlogon folder, then Shell and double click.
9. Change the value to explorer.exe.
10. Save your settings.

Getting rid of system malfunctions after upgrading to Windows 10 is not particularly difficult and does not require technical knowledge and skills from the user. After completing one of the operational procedures, the system will boot without delays or failures. Your computer will work better.

To understand why Windows 10 does not start, you need to determine after what actions the problem occurred: reinstalling programs or, removing system software or.

If before the problem the system worked stably and the black screen did not appear, then you may need to check the hardware of the device for a breakdown.

Computer won't turn on after update

In the window that opens, select the tile called “Diagnostics” and then the “Recovery” option. The system will do everything for you.

Wait a little and all the missing components will be installed and the computer will restart.

If Windows does not start after diagnostics and the black screen is still present, you should roll back the updates and return to the old version of the operating system.

Microsoft may not have fixed the installation issue for your device yet.

To roll back the OS to a previous version, use the above-mentioned diagnostic window. Click the diagnostics tile, then the advanced options tab.

Start System Restore:

In the window that opens, you will see all existing restore points and the date they were created. Select a point with the current date and click “Continue”.

In a few minutes, the newly installed system will be completely removed from the computer and, by restarting the computer, you will return to using the previous version of the OS.

Black screen when booting the system

If the system takes a long time to boot and you only see a black screen, you should try restoring the settings using the diagnostic window, as described in the previous paragraph of the article.

In most cases, the system restarts and starts working successfully again. Perhaps the black screen appeared due to incorrect installation of drivers.

A black screen at startup may be a result of your computer being infected with virus or spyware.

In this case, you should completely reinstall the operating system without saving any user files and programs, because they can transfer the virus to the new OS.

Windows 10 takes a long time to load

If the volume random access memory your device is less than 2 GB, slow work Windows 10 is quite normal.

Your computer's hardware cannot handle the updated OS version.

For more comfortable work, install one of the following on your computer previous versions Windows, it won't start for a long time.

Optimizing the operation of the OS includes the following steps:

• Removing all unnecessary programs from the startup menu. You can view the list of software that loads when you turn on the computer in Explorer; to do this, open the “Startup” tab;

Press the Ctrl+Shift+Esc and next buttons simultaneously to see all applications, just open the “Startup” section.

Then click on unnecessary program right-click and click disable.

• Scan your computer for malware using powerful antivirus software;
• Update the store and remove from it unnecessary applications, they can work in the background and load the system;

Creating a disk with a restored version of the OS

You can only create a recovery disk using a working OS on another computer. Go to the control panel and enter the following text in the search field: “recovery disk”.

After which you will see the following results. Click on the first one.

One of the most unpleasant and, it must be said, completely non-standard situation is when a black screen appears out of the blue during an update or after an update of Windows 10. The reasons for this phenomenon are unclear to many. And users begin to panic and search for a solution. But don't despair. Even if you are experiencing a black screen after updating Windows 10, there is a solution. By the way, it is also suitable for those who updated the installed eighth version to “ten”. Let’s make a reservation right away: it’s not that simple, so be patient.

Why is there a black screen after updating Windows 10?

In general, this situation is quite non-standard, since there are completely different cases. For example, a black screen (with or without a cursor) may occur when updating Windows 7, 8 or subsequent modification of 8.1 to the tenth version. It can also be observed in an already running Windows 10 during or after its own updates.

Let's look at several reasons that may influence this. As a rule, there are several of them:

• previous discrepancy installed drivers video cards;
• Explorer service failures;
• Fast startup enabled;
• re-licensing.

In addition, two more varieties are worth noting separately. Firstly, after upgrading to Windows 10, the black screen disappears after a while, and the system returns to normal. Secondly, the black screen “hangs” constantly, but the control elements (at least the keyboard) work. In principle, the solutions for almost all situations are generally the same. But let’s consider them based on the root causes (we are not talking about mechanical malfunctions of computer systems now).

Restoring the system using the standard method

So, after upgrading to Windows 10 - black screen and no reaction to boot again installed system. What to do? Naturally, the most simple solution It may be possible to restore the system to the original operating system if you have an installation disk or bootable flash drive.

All this is simple when a disk or flash drive is available. And if they are not there, what then? Don't give up. There is a way out: you can remove the black screen after upgrading to Windows 10 using built-in tools, and at the same time return to the old system. This is all the more good because the G8, when updated to the tenth version, is not destroyed, but is, so to speak, in a deactivated state.

What will need to be done? First of all, we call the “Task Manager” using the standard three-finger combination Ctrl + Alt + Del, and then in it we create a new cmd task (launch command line) running as administrator. In the window that appears, write the line shutdown /r /o /f /t 00, followed by a reboot.

Now in the action selection window we use diagnostics, after which we select system recovery in the additional parameters. When the process is complete, the computer will reboot again, and then the old working system will appear in front of you.

Windows 10: how to fix black screen during update?

The above situation is not the only one of its kind. In this case, the decision concerned exactly when a black screen appears after upgrading to Windows 10. But what should you do if it occurs precisely during the update process? The reason for this, apparently, is outdated graphics accelerator drivers.

If you see a black screen when installing Windows 10, in principle, you can do the simplest thing, although it may seem barbaric to many. We produce forced shutdown and reboot the terminal or laptop. When restarted, the system will check HDD for errors (maybe even in and load the desktop.

To prevent this situation in the future, we update the video card drivers. This can be done from the “Device Manager”, but if you have some utility like Driver Booster at hand, even better, because the driver will be downloaded from the manufacturer’s official website (and not only for the graphics chip, but also for all other devices that need in driver update) and then automatically integrated into the system. After this you can try to make Windows installation 10 again.

Entering Safe Mode

All this related to the fact that it was after upgrading to Windows 10 that the black screen was the result of system failures or conflicts with drivers. But what to do if the installation of “ten” seemed to be successful? And suddenly the cursor appears before the user’s eyes, but the system does not want to start, although the initial boot process clearly indicated that the system was trying to work?

It's not that simple. If there installation disk, there will be no problems. We perform the sequence as shown below (transitions from the diagnostic menu):

IN otherwise You will need secure login mode. But problems arise with him. The fact is that the standard pressing of the F8 key when starting Windows in the tenth version does not work (why it had to be removed is still unclear). However, not on all devices, but sometimes pressing F8 10-20 times while holding down the Shift key works.

In the next window, click on the continuation line and, finally, in the boot options window, press the F4 key (safe mode). Next comes a reboot, the system boots into safe mode.

How to restore your system in safe mode

In principle, even if “ten” was installed, you can easily return to the old system, however, with one caveat: if the user did not delete the files of the previous “OS”. Otherwise, nothing will work.

This can be done in the security and recovery section, where there is a special link to return to the previous system. That's all. The process will complete automatically, followed by a restart with the previously installed “seven” or “eight”.

If you need to restore the top ten itself after its own update, you need to command line(even at the boot stage) type the command sfc /scannnow and press the enter key (the scanning and recovery process is activated system files). The process can be quite lengthy, so you will have to be patient. You can reboot the system and check its functionality using the command shutdown -t 0 -r -f.

But when you enter safe mode, you can simply activate the recovery process and select control point, which preceded the emergence of such a situation.

Installing drivers and uninstalling updates

Another step that you can take when booting into safe mode relates to How to do this, which was described above, so there is no point in dwelling on this in detail.

As for the update packages that could cause this crash, you should go to the update center and look at the latest installed packages. Latest updates should be uninstalled, then set manual search updates, and those that caused a critical failure are excluded from the list. In principle, automatic updates can be disabled altogether. Windows doesn't recommend doing this, but there's nothing wrong with it. Updates mostly concern the security system, office applications, and only sometimes drivers. But if the user has the same Driver Booster package, the drivers will be updated through it. In addition, the program itself will issue a notification about the need for an update ( free version). Pro version This will generally update all drivers in the background. The user learns about this only from a message about successful installation.

Starting the Explorer service manually

Let's consider another unpleasant situation, when instead of the expected system start we have after loading Windows black screen and cursor (in some cases the cursor may be missing). The reason is a failure in the Explorer service, which was unable to load the Desktop. It will have to be launched manually.

We go to the “Task Manager”, as described above, after which we find the explorer.exe service in the process tree and forcefully terminate the process. Next, create a new task in the file menu and enter explorer.exe in the start line. If nothing happens, you can try to find the file yourself by clicking the browse button. As a rule, the file you are looking for is in the root Windows directories on system disk. This may partially solve the problem. As a last resort, we use the same safe mode and scan the system with recovery, as described above.

Enabling Fast Launch

Safe mode is also good because it allows you to change some key parameters that affect the performance of the system. Here we are talking about the so-called mode quick launch.

It is turned on from the power section in the standard “Control Panel”, where you first select the actions of the buttons, and then the unavailable parameters. Place a check mark next to the quick launch line, save the changes and reboot the system.

Getting rid of Windows Activation Technologies

Finally, one of the reasons may be reactivation. If copy of Windows licensed, there should be no problems, but sometimes the activation file is what causes trouble after upgrading to Windows 10. In this case, the black screen may “hang” constantly.

We use safe mode, in the folder properties we specify the display of hidden elements, after which we find the folder of the same name. As a rule, for 64-bit systems it is located directly in the system directory (C:\Windows), but for systems with 32-bit architecture it can be located in the System32 section, where you need to go first to the Tasks folder, then to Microsoft, and finally - Windows. We delete the folder with all its contents and reboot.

Conclusion

So we looked at the main causes of failures after upgrading to Windows 10. A black screen is, of course, an unpleasant thing, but, as we see, it is possible to deal with this type of failure, even if it occurs in an already working system. Naturally, some of the above methods will be somewhat difficult for many users to understand or apply in practice, however, if you show a little patience, you can fix the problem yourself, rather than running into some service center, and even pay money for it, albeit small, but it’s still a material cost.
