Issue

The system boot of a BitLocker encrypted system stops and it prompts you to enter the Bitlocker Recovery Key ID or perform the Bitlocker Challenge Response process.

First seen in


SafeGuard BitLocker Client 6.10.0

Operating systems
Windows 7, Windows 8, Windows 8.1

Cause

Several different scenarios can lead to this behavior, for example:

  • User forgets the TPM PIN (when PIN + PIN authentication is enabled).
  • User has lost the USB flash drive containing the startup key (when startup key authentication is enabled).
  • Moving the BitLocker-protected drive into a new computer.
  • Turning off, disabling, or clearing the TPM.
  • Updating the BIOS.
  • Updating critical early boot components that cause system integrity validation to fail (TPM).
  • Updating option ROM.
  • Installing a new motherboard with a new TPM.

What To Do

Follow the relevant recovery process offered by SafeGuard Enterprise. This will depend on the type of encryption used.

Encryption Type: Bitlocker  

The BitLocker Recovery Key ID can be obtained in the SafeGuard Management Center.

Open the SafeGuard Management Center, go to Tools | Recovery and follow the steps in the recovery wizard.

Encryption Type: Bitlocker C/R 

When starting the client, the user needs to press "any" key within the 3 second time-frame which is shown in a yellow font.

The "Challenge" code which is displayed needs to be entered in the SafeGuard Management Center in order to create the "Response" code for the client.

Open the SafeGuard Management Center, go to Tools | Recovery and follow the steps in the recovery wizard.
