Windows Boot menu locked asking for Bit locker key

Hi SOURAV PAUL,

The message you’re seeing is expected behavior when Windows detects a change in hardware, firmware, or security settings that prevents it from automatically unlocking the drive. In those cases, BitLocker requires the recovery key to ensure that only authorized users can access the data.

The recovery key is tied to the BitLocker key ID you mentioned (B00C1B7F-A8EE-471E-B7AE-6A983E45BCB7). To retrieve it, you’ll need to sign in with the Microsoft account that was used when BitLocker was first enabled. Once signed in at https://account.microsoft.com/devices/recoverykey (account.microsoft.com in Bing), you should see a list of recovery keys associated with your devices. Match the key ID displayed on your locked system with the one shown online, and enter that recovery key to unlock the drive.

If the device is part of an organization, the recovery key may be stored in Azure Active Directory or with your IT administrator. In that case, you’ll need to contact your IT team to obtain the key. Without the recovery key, the drive cannot be unlocked, as this is a core security feature of BitLocker.
