Bitlocker recovery problem

Hello Mina N,

Thank you for posting in Q&A forum.

Here are some steps you can follow to recover your BitLocker-encrypted drive:

1. You will need your BitLocker recovery key to unlock the drive. If you have saved it to your Microsoft account, you can find it by logging into your account on another device and checking the BitLocker recovery keys section.
2. If you are making hardware changes, you might need to suspend BitLocker protection temporarily. You can do this using PowerShell or the command line.

For example, you can use the command:

Manage-bde -protectors -disable C:

3. Ensure that the TPM is unlocked, Windows RE is enabled, and the system reserved partition is correctly formatted. You can use commands like get-tpm and reagentc to check these settings.
4. If your drive is corrupted, you can use the BitLocker recovery key and a backup drive to repair it. Run CMD as an administrator and use the command

repair-bde d: e: -rp {BitLocker Recovery Key} -force

Note: Where d is the corrupted drive and e is the backup drive.
