BitLocker Key Not Working on Alienware R17 with Windows 11

Question

My computer restarted, and now it won't boot after several attempts. It is asking for a BitLocker key, and I'm locked out of accessing anything on the device. I've entered the correct BitLocker key from my Microsoft account multiple times, but it returns me to the same BitLocker page.

The device is an Alienware R17 running Windows 11. I've also noticed that there are five different Windows 11 options available during previous restarts.

Hello,

Thank you for posting in Microsoft Q&A.

Based on the description, I understand your question is related to BitLocker Key Not Working on Alienware R17 with Windows 11.

Restart the computer, press and hold the F8 key as your computer restarts. The machine will show advanced boot options.

Select Repair your computer/Troubleshoot, and then open the Command Prompt.

Try run below command to check Bitlocker status on your machine:

manage-bde -status

You can also check the status of a specific drive, such as C drive:

manage-bde -status C:

If there is Bitlocker enabled drive, use below command to disable bitlocker of that drive:

Replace <recovery password> with your 48-digit recovery key, replace C with your current problem drive letter:

manage-bde -unlock C: -recoverypassword <recovery password>

After unlock, disable bitlocker use this command, replace C with your current drive letter:

manage-bde -off C:

Have a nice day.

Best Regards,

Molly
