Bitlocker Error after Image



  • Here is the error I am receiving when I try to Bitlocker a PC, post image.

    These steps are not for Windows 7, but they have worked for some Win7 users, so I thought I would give it a try. No Luck.

    1. Tried a “simpler” image.
      I took an HP 740 and gave it a basic image of a Win7 OS and it’s drivers. I then created an image on the Fog server, and then imaged a pc with that image. I still get the same error as above. My rationale was that some application had messedup my ability to bitlocker.

    2. Tried imaging an HP 740 with an image I create for an HP 8740. I can bitlocker this one, so something is not quite right with the image I created for the 740 / 840.

    Could this be something with the way I am Sysprepping the PC?

    Thank you for your assistance,

  • Found a solution!

    Long story short I took the laptop and installed Ubuntu. Then I installed Win 7 Enterprise, created a Fog image with this PC, and then used this to image the pc. Went to bitlocker it and it worked.

    So what does this mean? Apparently I was not able to take a Win 7 Pro laptop, out of the box, install Win 7 Enterprise, and bitlocker it. Windows, for whatever reason, does not like an OS to OS change. I must not be getting a clean install of Win 7 Enterprise. And I did remember to format the partition(s).

    Anyway, it took an unconventional approach to fix this problem.

    Now granted, the information I’m giving is to have bitlocker enable on systems during the sysprep/initialization phases occur, but it would seem to me that the system is attempting to load information from the generated BCD information of your system.

    Things to look for, I imagine, is the recovery information, system restore options, version of Windows, etc…

    Without knowing the exact variances between the 8740 and the 740/840 systems, such as hard drive, partition layouts, configurations, unattend information, I don’t know what’s wrong, but it leads me to believe it’s specific to the BCD and what BitLocker’s expectations are, not something you’re doing improperly (directly) because of the sysprep process you’re performing.

    The the info in this link might help?

    From what I’m gathering, you can’t pre-encrypt the drive for sysprep as the information gathered wouldn’t be able to be used across systems.http://support.microsoft.com/kb/929834/en-us
