Windows 10: unlock bitlocked e drive with key not working

my old c drive which is currently externally plugged in as a 'e: drive' is bitlocked and the only bitlocker key i have on my microsoft account is not working.

HELP: Automatic BitLocker Unlock.

Thank you sir, ill try your solution.

Windows Auto unlock ONLY works in case you have Bitlocker on your system drive, because if your system drive is not encrypted auto unlocking other drives means loss of security.
But in my case my system drive is Encrypted with hardware encryption that i password unlock during boot. So auto unlocking Bitlocker drives will do fine for me.

 

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!
