    Macrium Reflect - Issue Unlocking BitLockered Drive From Rescue Media


    Got Macrium Refect Free 6.3.1835 running well on Windows 10. Except when booting from Macrium rescue media, I cannot unlock my C: drive.

    My setup has a Bitlockered C: drive on a Samsung EVO 850 SSD, and my backup images are on E:, a portable BitLocker To Go USB3 HDD. My system is setup for UEFI/GPT boot.

    The BitLocker encryption on C: has the Samsung self encrypting drive (hardware encryption) feature enabled. Test booting from a Windows Recovery Drive allows me to unlock BitLocker for both drives in the restore mode, by entering the keys.

    In the Macrium Reflect Free rescue environment, I can open a command prompt and step through the manage-bde command lines to unlock E: (the external USB drive) just fine.

    But when I attempt to do so for C:, I always get an error. It appears that the Samsung drive is available to be the restore target, but will be wiped during a restore. That would require re-enabling BitLocker afterwards and generating new keys.

    The thing that puzzles me is that manage-bde is a Microsoft program, so I would expect it to work.

    Any thoughts are welcome. Thanks!

    Hello zzzoom,

    I do not recall if the Macrium free version allows for the addition of the Windows Bitlocker environmentals to the Macrium Rescue Media. I am a paid-version Macrium user.

    Hey, thanks for the reply!

    Yes it does. In fact you can create it two ways: 1) Include BitLocker support + automatically include keys; 2) Include BitLocker support without saving any keys.

    I have tried both methods with Rescue Media. I can unlock E: just fine, but neither method allows me to unlock my C: drive.

    I am posting here because you need a licensed product to join the Macrium forum. Hoping someone here can point out something I may be overlooking.

    Itīs not clear to me what do you mean by:

    "The BitLocker encryption on C: has the Samsung self encrypting drive (hardware encryption) feature enabled."

    Are you using BitLocker or a different Samsung encryption? Or both?

    Simple. Enable 'Encrypted Drive' in Samsung Magician. Reboot. Enable BitLocker in Windows 10. The entire drive is instantly BitLockered. No software encryption layer is necessary.

    I revisited this issue again yesterday. I am now running Macrium Reflect Free 7.1.2917, so with a fresh build of Win PE on my rescue media, I thought I would try again.

    Still no luck with accessing or unlocking my encrypted Samsung SSD system drive. However unlocking my encrypted external USB drive, which is my image repository, works just fine. Can browse to the image to restore OK.

    I realize that a workaround would be to just use 'Manage Bitlocker > Turn off BitLocker' from within Windows before attempting a restore. But I am assuming that in case I ever needed to restore, perhaps it's a good possibility that Windows would no longer boot. In that case I suppose I could also use the Samsung Magician boot utility 'Secure Erase' to reset my SSD to factory settings.

    But I am really trying to understand why I cannot unlock my BitLockered C: drive. Whenever I attempt to use 'manage-bde –unlock C: -recoverypassword 111111-222222-333333-444444-555555-666666-777777-888888' from within the Macrium rescue environment, I get 'ERROR: an error occurred (code: 0x80070057)'.

    If I boot from a Windows repair disk, I can enter the keys and unlock both drives.

    Weird.

    Here is a command window showing the 'manage-bde -status' for the two encrypted drives.
