Bitlocker problem

Question

My screen has put me into Bitlocker recovery. I do not have a key number and don’t think I created one. How do I go forward.

Answer 1

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, 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.

https://account.microsoft.com/devices/recoverykey

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.

If you are unable to find the Bitlocker Recovery Key on any account that may have been used on that device, then I am sorry for the bad news, a Windows reset will not work on an encrypted drive, the only way to access that device is to create a bootable Windows 11 USB on another working PC and use that to clean install Windows and at the start of the installation, delete all partitions on the drive to remove the encryption, which will sadly result in loss of all data on the drive.

Answer 2

BitLocker always creates a recovery key when it is turned on, but it may have been saved somewhere without being noticed. To move forward, the recovery key must be found; if it cannot be found, the only option is to reset the device and lose the data on the encrypted drive.

Follow these steps in order:

1. Note the Recovery Key ID
   • On the blue BitLocker recovery screen, write down the first 8 digits of the Recovery key ID. This helps match the correct key if multiple keys exist.
2. Check if the key is in a Microsoft account
   • From another device, open a browser and go to: https://aka.ms/myrecoverykey (redirects to the Microsoft account BitLocker keys page).
   • Sign in with the same Microsoft account that was used on the locked PC.
   • Look for a key whose Key ID matches the first 8 digits shown on the BitLocker screen.
   • If found, use the corresponding 48‑digit recovery key on the BitLocker screen (hyphens are optional).
3. Check if the key is in a work or school account
   • If the device was ever joined to an organization or signed in with a work/school account:
     1. On another device, go to https://aka.ms/aadrecoverykey.
     2. Sign in with the work or school account.
     3. Select Devices, expand the affected device, then select View BitLocker Keys.
     4. Match the Key ID and use the corresponding 48‑digit key on the BitLocker screen.
4. Look for other backup locations
   • Printout: Check any printed documents kept with important PC papers; the printout will show a Key ID and a 48‑digit key.
   • USB flash drive: If the key was saved to a USB drive:
     • Plug that USB into another PC and open the text file containing the key, or
     • Plug it into the locked PC and follow the on‑screen instructions if prompted.
5. If the key cannot be found
   • If the device is managed by an organization, contact its IT support; they may be able to retrieve the key.
   • If the key cannot be found in any location and the change that triggered recovery cannot be undone, the only way forward is to reset the device using Windows recovery options. This will remove all files on the encrypted drive.
   • For reset options, see: Windows recovery options.

Without the BitLocker recovery key, the encryption cannot be bypassed or unlocked by Microsoft Support or anyone else.
