BitLocker Recovery Key
What is Windows BitLocker?
- The BitLocker Drive Encryption security feature in Windows protects files on your computer in the event that anyone tampers with the computer's startup process.
- BitLocker can leverage the Trusted Platform Module (TPM) security hardware to guard data and system files in the Windows operating system directory, and also protects early boot component integrity.
- Encrypting the entire Windows volume with BitLocker can help prevent others from seeing your files, even if your computer is stolen or a hard disk removed.
Bitlocker Errors
- If you see either of the prompts below, please contact the Help Desk at x71945 immediately for remediation.
-
The bitlocker recovery prompt can occur for for the following reasons:
- System board or other hardware failure to include the hard disk.
- Windows updates, specifically ones that update hardware drivers.
- Changing the BIOS boot order to boot another drive ahead of the hard drive
- Having CD or DVD drive ahead of the hard drive in the BIOS and inserting or removing a CD/DVD
- Failing to boot from a network drive before booting from the hard drive
- Docking or undocking a portal computer if the computer was (respectively) undocked or docked when Bitlocker was turned on
- Changes to NTFS partition table on the disk including: Creating, Deleting, or Resizing the primary partition.
- Entering PIN incorrectly too many times, activating the anti-hammering logic of the TPM
- Turning off BIOS support for reading USB devices in the pre-boot environment if you are using USB-based keys instead of PIN T
- urning off, disabling, deactivating, or clearing the TPM
- Upgrading critical early startup components such as BIOS upgrades
- Forgetting the PIN with PIN authentication
- Updating option ROM firmware
- Upgrading TPM firmware Adding or removing hardware
- Removing, inserting, or completely depleting the charge on a smart battery (portal computer)
- Changes to the master boot record (MBR) on the disk
- Changes to the boot manager (bootmgr) on the disk
- Hiding the TPM from the operating system
- Using a different keyboard that doesn’t enter the PIN correctly or one that doesn’t map as assumed by the pre-boot environment
- Modifying the Platform Configuration Registers (PCRs) used by the TPM validation profile
- Moving the Bitlocker-protected drive to a different system
- Upgrading the motherboard to a new one with a new TPM
- Losing the USB flash drive containing the startup key with startup key authentication enabled
- Failing the TPM self-test
- Having a BIOS or an option ROM component that is not compliant with the relevant Trusted Computing Group standards for a client computer
- Changing the usage authorization for the storage root key of the TPM to a non-zero value
- Disabling the code integrity check or enabling test signing on Windows Bootmgr
- Pressing the F8 or F10 key during the boot process
- Adding or removing add-in cards (such as video or network cards), or upgrading firmware on add-in cards
- Using a BIOS hot-key during the boot process to change the boot order to something other than the hard drive

Requesting a BitLocker Key
-
If your machine will not boot and you are prompted for a BitLocker key, provide the following to the Help Desk.
- Computer Name or Serial Number / Service Tag (From the bottom of the computer)
- Your Name, NetID, and department.
- Verification of identity. This can either be done by sending a photo of a Government ID to help@georgetown.edu or by calling 202.687.4949 and verifying your identity over the phone.
- If this happens often, there is likely a hardware issue with your computer and it may need to be serviced.
Use Cloud Backup
- Issues can happen at any time. Be sure your files are stored in cloud or an external storage device.
