Solution Steps
- 1 Restart your PC. Sometimes a simple reboot can fix the issue if it was a temporary glitch. If the BSOD appears again, proceed to the next steps.
- 2 If you can boot into Windows, press Windows key + X and select 'Windows Terminal (Admin)'. Type 'chkdsk C: /f /r' and press Enter. You may need to schedule it for the next restart. This command checks the disk for errors and repairs them. It's like a mechanic inspecting your fuel lines for blockages.
- 3 If you cannot boot into Windows, insert your Windows 11 installation USB and boot from it. Choose your language, then click 'Repair your computer' → Troubleshoot → Advanced options → Command Prompt. Type 'chkdsk C: /f /r' and press Enter. This will scan and repair the boot drive.
- 4 In the same Command Prompt, type 'bootrec /fixmbr', 'bootrec /fixboot', and 'bootrec /rebuildbcd'. These commands repair the boot configuration. They are like resetting the ignition system of your car.
- 5 If the issue persists, the hard drive might be failing. Use a tool like CrystalDiskInfo (if you can boot) to check the health of your drive. If it shows errors, consider replacing the drive. If you have a spare drive, you can clone your system or reinstall Windows.
