At times, when you boot your Windows 11/10/8/7 system, you may reach up to the Welcome screen, but then it stays blank. While there are a lot of fixes being posted, the one I am posting now is the one that worked for me and a few people I helped.
Windows 11/10 boots to Blank or Black Screen
1] Run Automatic Startup Repair
The first step I recommend is to run the Startup Repair because it’s used to fix boot issues. It would check the consistency of files required to boot like Boot Manager, etc.
2] Run System File Checker
If Startup Repair fails then the next step is to run System File Checker. I know your system won’t boot but you could run from Recovery Tools.
Click on “Command Prompt” and run SFC /SCANNOW.
3] Restore Master Boot Record
If this does not help, then we have to Restore MBR. Sometimes a bad MBR can cause the system not to boot. We will have to use the Bootrec.exe Tool.
4] Run Black Screen Troubleshooter
You can also use the online Black Screen Troubleshooter from Microsoft and see if that helps.
