This article describes the steps that you can use to restore Windows 8.1 without deleting user data.

If the malfunctions of the computer cannot be eliminated by the usual methods, one radical solution remains - reinstalling the operating system. Many users are intimidated by the prospect of reinstalling the system.

In Windows 8.1, the problem of reinstalling the operating system is practically solved. Of course, the operating system will not do everything for you, but many users who previously called the wizards or experienced acquaintances to reinstall the operating system, will now be able to do it themselves. The fact is that in Windows 8, Windows 8.1 a new reset function has appeared, which allows you to quickly, literally in a few clicks, restore the operating system or return it to its original state.


In the event of a serious system malfunction that cannot be eliminated by the usual methods, you can restore the operating system to operability, while preserving your personal files, accounts and contacts. To do this, you need to reset the operating system. We need a Windows 8.1 installation disc or a bootable USB flash drive with Windows 8.1

Press the keyboard shortcut + I, in the panel that opens Parameters click Change computer settings

A window will open Computer settings, choose Updating and restoring

In the window Updating and restoring push Recovery

A little waiting

If your computer does not have an active Windows 8.1 recovery partition, the system will display a warning. You will need a Windows 8.1 installation disc or a bootable Windows 8.1 USB stick

Insert the Windows 8.1 installation disc or a bootable Windows 8.1 USB stick. The update wizard window will open, which lists the consequences of the update, namely:

● Your files and personalization settings will not change.
● Computer settings will be restored to their default values.
● Windows Store apps will be saved.
● Applications that you installed from discs or websites will be removed.
● The list of removed applications will be saved on your desktop.

If you accept the above terms, click Further

The computer will restart and the system recovery process will begin.

System recovery may take some time. The recovery time can range from several minutes to several tens of minutes (depending on the speed of the computer).

Recovery is fully automatic. Your presence at the computer is optional. After completing the recovery process and restarting, your computer is ready to go. You just have to install the programs that were removed as a result of the system restore. All of your accounts and passwords will remain intact, so use your old password to log in.

but such a glitch jumps on windows 8.1 too. I recently upgraded the OS on a laptop. Before that, I had windows 8, so now, as you know, it's windows 8.1. However, in this article I will not talk about all the delights of the OS, but I will tell you about the problem I had to face. And the problem is this: as soon as the update process came to an end, everything worked well, but the next time the laptop was turned on, I had to look at.

At first I thought I had to wait, maybe it hasn't loaded yet, but no. No matter how much I waited, no matter how much I moved the cursor across the screen, nothing changed. I immediately began to look for a solution to this problem. And, as you already understood, I found it!

Here I will try to clearly explain step by step all my actions that will help you fix a black screen in Windows 8.1 and not only. This is how the white cursor looks like, on a black background.

Remove the black screen at boot

The first way

To begin with, the question arises: "How can you do something if there is nothing on the screen?" I got out of this situation in an interesting way. I put the laptop to sleep. Oddly enough, but upon waking up, everything was fine, there was no black screen. Since when I press the shutdown button, my default is to fall asleep, it was enough to press it. If for some reason you cannot do this, or it does not work out, you will have to use an alternative method.

Second way

You will have to run a program on your computer that, when closed, brings up dialog boxes such as "save" (paint, word, excel, etc.). After you have launched the program, turn off your computer (but not from the outlet). As a result, you will be given a warning that something has not been saved. Just at this moment, the screen should work.

Third way

On one forum, I read that if you turn on the computer with the Internet turned off, then everything will go off with a bang! I myself have not tried this method, so you should test it. Maybe someone will come in handy :).

Preventing the problem

When you were able to get rid of the black screen, you need to make sure that the next time you start your computer, it will not be there. So, let's begin.

  1. Go to Control Panel.(Options -\u003e Control Panel)

In the menu that opens, select "Power supply".

On the left, select the item "Prompt for password on wakeup"

Click on the inscription "Changing parameters that are currently unavailable"

Then we uncheck the box "Enable Fast Startup (Recommended)".

After the steps taken, everything should work fine.

4. Method

In order to stop constantly showing the black screen, you need to: boot into safe mode


addition: "just like that, you can't find Windows Activation Technologies in drive C, you need to set a search (for example, I set a search on my computer for" wat.exe ") and then it will find"
Helped a lot! It remains only to activate

5. A way to remove the problem with a black screen and cursor

This method is similar to the fourth, but here we will not use safe mode, but try to get out through the "Task Manager". And so you have a black screen when loading windows 8.1 and the cursor blinks. Press the magic key combination (Simultaneously) CTRL, ALT and Delete.

Select "Task Manager"

In the window that opens, click the menu "File - Run new task"

Let's start the Windows Explorer process by entering explorer.exe.

You will see "My Computer", then as in method 4, you must delete the C: \\ Windows Activation Technologies folder and make sfc / scannow from powershell or command line under the administrator.

6. Method

If you have a laptop, then try connecting a monitor to it, this is done either through the VGA output or HDMI. There is a high probability (if the integrated adapter is not disabled in UEFI) that after enabling, you will see an image on the screen and will be able to roll back the discrete video card drivers (through the device manager), install new ones, or use system restore.

7. A way to remove the black screen at the entrance

This method is based on the assumption that you have caught a computer virus somewhere. In order to fix the black screen of Windows 8.1 due to a computer virus, do the following. As in the 4th method, boot into safe mode, preferably without a network, or simply unplug the Internet cord. If you immediately have a black screen, then, as in the 4th method, call the task manager, but for the place of the explorer.exe process, type regedit and press Enter.

This will open the Windows Registry Editor. Go to the branch:

HKEY_LOCAL_MACHINE \\ SOFTWARE \\ Microsoft \\ Windows NT \\ CurrentVersion \\ Winlogon \\

Find a key named "Shell" here and make sure that it has explorer.exe in its value. If not, then change it to the desired one, insert a USB flash drive with some kind of dr web cureit or Kaspersky free, and try to heal the system. As soon as you kill the virus, you will no longer have black screens in the Windows 8.1 operating system.

8. Method

In the same safe mode, try uninstalling the video driver, this is done through the device manager, right-click on start and select the device manager item.

Select the item video adapters and right-click on the desired one, and select delete. After that the system will load the standard drivers, reboot.

Black screen after installing updates

Very often Microsoft gives us a pig with updates, I agree that they are necessary and close gaps in the OS, but once a quarter I see situations when they break systems for nothing, here's an example of error 9c59 or 0x800705b4. If you have become hostage to such a situation, and you have a black screen on your laptop, for this reason, then try to return to the restore checkpoint. These points are created whenever anything is installed on Windows. It helps 99% of the time.

Black screen on Windows 8.1 laptop due to Crypto PRO

I have caught problems many times with this encryption software product. For example, Windows installer service could not be accessed, and here this thing puts a spoke in the wheel. For some reason, the HKLM \\ Policy \\ PolAdtEv registry branches are missing.

Here the actions are as follows, you need to uninstall Crypto PRO, then when the problem with the black screen is fixed, you will install the latest version. As in method 4, invoke the task manager, but in the run window enter "appwiz.cpl". This will open the Programs and Features snap-in, where you will need to uninstall Crypto PRO.

Hope that thanks to these methods, you were able to fix the problem with black screens in the Windows 8.1 operating system ..

If your computer cannot find the system, does not enter Windows, reporting that it cannot find the bootable disk, and automatic error correction does not help, most likely correcting the boot records will help you.

Correcting MBR boot records and BCD boot configuration in many cases helps to solve system startup problems that can occur due to an unexpected power off of the computer, software failures, viruses, and many other reasons. Fortunately in the Windows operating system. starting with version 7, there are built-in boot loader repair tools, which will be discussed in this article. Third-party Windows startup repair programs are largely based on the built-in utilities, so the use of additional programs to repair the bootloader is not necessary.
Everything described in this article applies to Windows 7 and Windows 8.1, but should work for the new Windows 10 as well.

Bootrec.exe - Windows boot error fixing utility

Bootrec.exe is the "very" built-in utility from Microsoft, which we will run from the command line.
At the same time, we will run the command line not inside running Windows (even because the system is not working for us at the moment), but in a slightly different way:

If you can start the command line, enter the command in it bootrec.exe, thus it will be possible to get acquainted with all the available commands of this utility. In general, their description is quite clear, but just in case, we will define each of the functions and describe the cases in which these functions can be useful.


Writing a new boot sector

Running command bootrec.exe with parameter / FixBoot allows you to write a new boot sector to the system partition of the hard disk, while using a boot partition compatible with the installed operating system - Windows 7 or Windows 8.1.

This parameter is useful in cases when:

  • The boot sector could be damaged (for example, after software failures, changes in the structure and size of hard disk partitions, errors in user actions, etc.)
  • An older version of Windows was installed after a newer one (for example, if you installed Windows XP after Windows 8.1)
  • An incompatible Windows boot sector was written.

To write a new bootloader, simply run bootrec with the specified parameter, as shown in the picture below. To check if this operation fixes startup problems, simply restart your computer. If not, you can move on to using other parameters of the bootrec command.


Fix MBR (Master Boot Record)

The second bootrec.exe parameter to study is FixMbr, which allows you to fix the MBR or the Windows bootloader. When using FixMbr, the damaged MBR is simply overwritten with a new one. The boot record is usually located on the first sector of the hard disk and tells the BIOS of the computer how and from which partition to start loading the operating system. If damaged, you may encounter the following errors that appear on a black screen when the computer boots:
  • No bootable device
  • Missing operating system
  • Non-system disk or disk error
  • In addition, if you suddenly get a message that the computer is locked even before the virus starts loading Windows, fixing the MBR bootloader can also help.


To run the boot record repair, enter at the command line bootrec.exe /fixmbrand press Enter. As in the first case, in order to make sure that this operation has corrected the problem of starting the system, just restart the computer.

Finding installed Windows in the boot menu

If your computer has multiple Windows systems older than Vista, but not all of them appear in the boot menu, you can try running the command bootrec.exe / scanos to find all partitions of installed systems.



If installed Windows systems are found on your computer, then to add them to the boot menu, use the command to re-create the BCD boot configuration repository.

Rebuilding BCD - Windows Boot Configurations Store

In order to reconfigure BCD and add to its list all installed Windows systems lost for any reason (as well as recovery partitions created on the basis of Windows), use the third command to study bootrec.exe / RebuildBcd.



In some cases, if these steps do not help, it is worth trying the following commands before performing a BCD rewrite:
  • bootrec.exe / fixmbr
  • bootrec.exe / nt60 all / force

Conclusion

As you can imagine, bootrec.exe is a built-in utility for working with Windows boot loaders, as well as a powerful tool for fixing various Windows boot errors. It is on the use of this utility in the command line that the work of many similar programs for restoring Windows boot is based, as well as the work of many computer repair specialists.
