How to fix BitLocker recovery screen loop

Error code: BITLOCKER-RECOVERY-LOOP

What this error means

The system is stuck in a BitLocker recovery screen loop, repeatedly asking for a 48-digit recovery key. This occurs when the TPM chip detects that the boot configuration has changed (BIOS update, new hardware, Secure Boot toggle), invalidating the stored encryption keys. Entering the recovery key once should resolve it, but the loop indicates the underlying trigger persists.

Updated

Before you begin

Save open work and back up important files. Use instructions for your exact device and software version. If Windows cannot start, see the startup guide.
