Hello!
I'm Yasllame.
I'm happy to help and clarify.
If you have already entered your BitLocker recovery key but Windows 11 still does not boot, it usually indicates that the issue is not only related to BitLocker but also to how Windows is loading after the update. First, check whether your recovery key was accepted correctly—if it loops back and asks again, the key may not match the right drive. If it is accepted but Windows fails to load, you can try booting into the Windows Recovery Environment by restarting your computer three times in a row during startup to trigger the recovery menu. From there, go to Troubleshoot > Advanced Options > Startup Repair to let Windows attempt to fix boot issues. If Startup Repair does not work, open Command Prompt from the same menu and use commands like bootrec /fixmbr,bootrec /fixboot, and bootrec /rebuildbcd to rebuild the boot configuration.
If none of these work, you may need to temporarily suspend or disable BitLocker from the recovery environment using the command manage-bde -off C: (replacing C: with your system drive letter), but be aware this will start decrypting the drive and can take time. If the update corrupted system files, you can also use sfc /scannow or DISM /Online /Cleanup-Image /RestoreHealth inside recovery.
If the system remains stuck, the last option is to create Windows 11 installation media on another PC and perform a repair install or reset while keeping your files. Would you like me to detail the exact recovery
I hope this information was helpful! If you need anything else, I'm here.
