BitLocker recovery requires the correct 48‑digit recovery key. If the key cannot be found, Windows cannot be unlocked or reset without data loss.
Follow these steps in order:
- Enter the BitLocker recovery key On the BitLocker recovery screen, type the 48‑digit key (hyphens are optional). If the key is correct, Windows will start normally.
- Find the BitLocker recovery key
If nothing appears at aka.ms/myrecoverykey, check all possible locations listed in the official guidance:
- Microsoft account (for personal devices) – sign in and check all profiles that might have been used on this device.
- Work or school account / Intune – if this is an organization‑managed device, the key may be stored in Azure AD/Intune. An IT admin can retrieve it using the Intune “Get recovery key for Windows” process.
- Printed copy, USB drive, or file – check any printouts, USB sticks, or files where the key might have been saved when BitLocker was first enabled.
- Organization helpdesk – if the device is managed by a company or school, contact the IT department; they may have escrowed the key.
- If the recovery key cannot be found
- Without the BitLocker recovery key, the encrypted drive cannot be unlocked. None of the Windows recovery options (Automatic Repair, Reset this PC, Startup Repair, reinstall) can access the data without that key.
- If the key truly cannot be located in any of the places above, the only remaining option is to wipe/repartition the drive and reinstall Windows. This will permanently erase all data on the encrypted volume.
- Reinstall Windows if recovery options fail
If Automatic Repair and other recovery options do not work, and the BitLocker key is available or the drive has been wiped:
- On another working PC, create Windows 11 installation media (USB/DVD) from Microsoft’s official download page.
- Boot the affected PC from that installation media.
- If the drive is still BitLocker‑encrypted and you have the key, enter it when prompted so Setup can access the drive. If you do not have the key, delete the encrypted partitions during setup and install Windows to the unallocated space (this erases all data).
- Complete Windows setup.
If this is a work or school device, contact the organization’s IT admin and explicitly ask them to retrieve the BitLocker recovery key from their management system (Azure AD/Intune/AD) before attempting any reinstall.
