Dear Raguraman S,
Thank you for reaching out to the Microsoft Q&A Forum.
I recognize that encountering a persistent BitLocker recovery cycle, despite providing the valid 48-digit credential, is a significant workflow interruption. This behavior typically indicates that the Trusted Platform Module (TPM) or the Boot Configuration Data (BCD) is struggling to validate the system state after the key is accepted, causing the system to revert to a locked state for protection.
Since you possess the correct recovery key, we can utilize the Windows Recovery Environment (WinRE) command line to manually unlock the drive and temporarily suspend the verification mechanisms to break this loop. Please follow these steps:
- Accessing the Command Prompt:
- On the BitLocker recovery screen, if there is an option to "Skip this drive" or "Advanced repair options", select it. If these are not visible, force the device to shut down and power it on. Repeat this 3 times to trigger the Automatic Repair environment.
- Navigate to Troubleshoot > Advanced options > Command Prompt.
- You may be asked to select your account and enter your password.
- Manually unlocking the drive:
- Check the status of your drives to confirm the volume letter (usually C: or D:). Type the following and press Enter:
manage-bde -status - Look for the volume where "Conversion Status" is "Encrypted". We will assume it is C: for these steps.
- Unlock the drive manually using your 48-digit key. Type the following command (replace the X's with your actual key) and press Enter:
manage-bde -unlock C: -rp XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX - If the output says "The command has been successfully completed," the drive is now accessible.
- Check the status of your drives to confirm the volume letter (usually C: or D:). Type the following and press Enter:
- Suspending BitLocker protectors:
- Type the following command and press Enter:
manage-bde -protectors -disable C: - You should see a message stating "Key protection is disabled."
- Type
exitand press Enter to close the Command Prompt. - Select Continue to boot into Windows.
- Type the following command and press Enter:
- Re-enabling protection:
- Type "Manage BitLocker" in the Start menu search bar and open the control panel.
- You will likely see the drive status as "Suspended".
- Select "Resume protection".
I hope these steps could help. If you have any further issues, I'm here to assist.
