Yes. The number BitLocker is asking for is the 48-digit recovery key, sometimes called the recovery password. On the recovery screen, enter that 48-digit key. Hyphens are optional.
If the laptop keeps asking for it on every startup:
- Use the correct 48-digit recovery key to start Windows.
- After Windows opens, check why recovery is being triggered:
- Open an elevated Command Prompt.
- Run
manage-bde.exe -status to view the current BitLocker protection mode and configuration.
- If the issue started after a change such as firmware, boot, or TPM-related changes, BitLocker protection can be reset by suspending and resuming BitLocker.
- If the problem is a forgotten BitLocker PIN:
- Unlock the device using the recovery password.
- Open the BitLocker Control Panel applet.
- Expand the drive and select Change PIN.
- Select Reset a forgotten PIN.
- Enter and confirm the new PIN, then select Finish.
If the device shows recovery because of Secure Boot changes:
-
E_FVE_SECUREBOOT_DISABLED: re-enable Secure Boot and reboot. If that does not fix it, a recovery method is required.
-
E_FVE_SECUREBOOT_CHANGED: a recovery method is required to unlock the device.
If the recovery key was never backed up, BitLocker does not automatically back it up later. Existing recovery information can be backed up manually with manage-bde.exe.
