Hi douglas connelly,

Welcome to the Microsoft Q&A forum.

Thanks to Q&A Assist, your data is accessible and can be copied safely. You can choose one of the quick methods below to process:

Option 1: Copy files using a simple file window

• In the Command Prompt screen, type: notepad
• In Notepad, select File > Open.
• Change File type to All Files.
• Use the file window to browse your unlocked drive.
• Insert a USB drive, then copy and paste your files to it.

Option 2: Copy files using commands - This option is faster and more reliable for large amounts of data

• Identify drive letters:

diskpart
list volume
exit

• Copy files to a USB drive using: robocopy C:\Users E:\Backup /E /Z (Adjust drive letters as needed).

Your drive unlocking successfully confirms your data is intact. Taking a backup now is a smart next step and helps ensure peace of mind before moving on to system recovery.

Answer 4

The BitLocker key was accepted, but Windows is still not booting and reports that the drive is locked. Use the recovery key again to fully unlock the drive, then repair or reinstall Windows.

Follow these steps:

1. Unlock the drive from Windows Recovery Environment (WinRE)
   1. From the BitLocker recovery screen, enter the 48‑digit recovery key so the device can proceed into recovery.
   2. When you reach the recovery options, choose Troubleshoot > Advanced options > Command Prompt.
   3. In Command Prompt, identify the Windows drive letter (often C: in normal Windows, but in WinRE it may appear as D: or another letter). You can check by running:

            dir C:\
            dir D:\
      

      and looking for the Windows folder.
   4. Once the correct drive letter is known, unlock it explicitly with manage-bde using the recovery password:

            manage-bde -unlock <DriveLetter>: -recoverypassword <48-digit-key>
      

      Replace <DriveLetter> with the drive that contains Windows and <48-digit-key> with the BitLocker recovery key.
2. If the drive is still reported as locked If Windows still says the drive is locked or cannot be accessed even after unlocking with the recovery key, connect the drive to another working PC as a secondary drive and unlock it there:
   1. Attach the drive to another Windows device.
   2. On that device, unlock the BitLocker‑protected volume using either PowerShell or Command Prompt, for example:

            Unlock-BitLocker -MountPoint D -RecoveryPassword xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx
      

      or

            manage-bde.exe -unlock D: -recoverypassword xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx
      

   3. After unlocking, copy important data off the drive to another location.
3. If Windows remains unbootable after unlocking After data is backed up, use installation media or the PC’s recovery image to perform a repair install or a clean install of Windows. If doing a clean install from bootable USB and deleting all partitions, BitLocker keys are not required because the disk is being fully repartitioned and reformatted.
4. If the volume is damaged and cannot be unlocked normally If the recovery password is correct but the volume is damaged and cannot be unlocked, use the BitLocker Repair tool (repair-bde.exe) as a last resort to salvage data, provided the BitLocker key package and recovery password are available. This tool decrypts the volume at block level to recover data from severely damaged drives. It cannot repair drives that failed during encryption/decryption and assumes the drive is fully encrypted.

If none of these methods can unlock the drive or recover data, and no backup exists, data on the drive may not be recoverable.
