Hello,
Thank you for posting in Microsoft Community forum.
Based on the description, I understand your question is related to bitlocker.
1.Double-check the password you entered. Ensure that there are no typos or mistakes.
- If you have a BitLocker recovery key, try using it instead of the password.
- If your computer is part of a domain, ensure that you’re using the correct domain account credentials.
If it’s a standalone system (not part of a domain), use the local account credentials.
- Make sure you’re trying to unlock the correct drive. Sometimes, multiple drives are encrypted, and you might be entering the password for the wrong one.
Have a nice day.
Best Regards,
Molly
