Dealing with a blank login screen on Windows 10 or 11 can be a frustrating experience. It can prevent you from accessing your computer, and it may not even allow you to boot into Safe Mode. Fortunately, there are several steps you can take to troubleshoot the issue and get your computer running properly again.
Here’s what you can do to fix a blank login screen in Windows 10 and 11:

1. Check your monitor and display settings

Before you start tinkering with your system, the first step is to make sure that your monitor and display settings are set up correctly. Ensure that the input and display cables are properly connected, and check that your monitor is turned on.

If you’re using an external monitor, make sure it’s set to the correct input source. Also, check that the resolution and

refresh rate are set correctly by going to the settings and adjusting them as necessary.
2. Boot into Safe Mode

To boot your computer into Safe Mode, start your system, press Shift + F8, and then select Safe Mode from the menu. Alternatively, you can also try pressing F8 repeatedly during the boot process, and select Safe Mode from the

Advanced Boot Options menu.

If you can boot into Safe Mode, try updating your drivers or rolling back to an earlier version. If Safe Mode doesn’t work, then proceed to the next step.

3. Run a startup repair
If you’re still having issues, then try running system repair or startup repair. To do this, boot into the Windows Recovery Environment by pressing the F8 key repeatedly during the boot process, and then select Troubleshoot > Advanced options > Startup repair.

The repair process may take some time, but once it has finished, try logging in again to check if the issue has been resolved.

4. Restore your system

If the startup repair doesn’t work, then you may need to restore your system to a previous point. To do this, boot into the Windows Recovery Environment, and select Troubleshoot > Advanced options > System Restore.
Select a restore point that was created before the issue began, and let the process finish. Once it’s done, try logging in again to check if the issue has been resolved.

5. Refresh or reset your system

If none of the above steps works, then you may need to refresh or reset your system. To do this, boot into the Windows Recovery Environment, select Troubleshoot > Reset this PC.
Choose either the Refresh or Reset option, depending on your preference. Note that resetting your system will delete all your files, so make sure to backup everything important before proceeding.
