Bit locker locked drive

If your drive is encrypted with Bitlocker, the only place the Bitlocker Recovery key is automatically stored is on the associated Microsoft account on the link below, if you have found a Bitlocker Key and it is not working to unlock the drive, be sure to check any Microsoft account that may have been used on the PC and also any work or school account that may be linked to the PC.

(Note, even if your device does not show on the Microsoft account, the Bitlocker Recovery Key may still be available on this link)

Are you able to find the Bitlocker Recovery Key on any account that may have been used or linked to the laptop?

If not, do you have a safe backup of your files, or use a cloud service like OneDrive to sync your files online.

Use the 48‑digit BitLocker recovery key to unlock the drive. On the blue BitLocker recovery screen, carefully type the full 48‑digit key (hyphens are optional). If the key is correct, Windows should start normally.

If entering the recovery key on the device does not work, try these steps:

1. Verify the correct recovery key
   • If multiple BitLocker keys exist, make sure the first 8 characters of the Recovery Key ID shown on the BitLocker screen match the key being used.
   • If the key is stored in a Microsoft account, sign in to https://account.microsoft.com/devices/recoverykey or follow the guidance in Find your BitLocker recovery key to confirm the correct key.
2. Try entering the same key again
   • Some users report that re‑entering the same correct key multiple times eventually allows Windows to continue, especially if an update is in progress.
3. Unlock from another device (if Windows will not boot)
   • Remove the drive and connect it as a secondary drive to another Windows device.
   • Unlock it using PowerShell:

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

   • Or use Command Prompt:

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

4. If the recovery key still does not unlock the drive
   • If the correct recovery key cannot be found or does not work, BitLocker protection cannot be bypassed. BitLocker is designed so that without a valid recovery key, the data cannot be decrypted.
   • In that case, the only remaining option is to delete the encrypted contents (for example, by formatting the drive and reinstalling Windows), which results in data loss.

If the drive is severely damaged and the correct recovery password does not unlock it, the BitLocker Repair tool (repair-bde.exe) can be used together with the BitLocker key package to attempt block‑level decryption and salvage data, provided the necessary key material is available.

After successful recovery and boot into Windows, reset the root cause so the device does not repeatedly enter recovery (for example, reset a forgotten PIN, replace a lost startup key, or suspend/resume BitLocker after firmware changes).
