Restore FROM Bitlocker enabled External USB drive
I have been forever backing up my (non Bitlocker) hard drive to my Bitlocker enabled external USB drive. Now's the time for a restore and after selecting the backup and commencing the restore, after reboot, I'm getting a message saying the drive containing my backup cannot be found/read. I'm guessing it's because the Acronis Restore cannot recognise the external drive because I'm not in the OS yet and it's because the OS contains the Bitlocker key?
What is the solution for this (other than disabling bitlocker on the drive in question)?
Thanks

Hi all,
I have a quite similar question so will ask it here :
Does the normal "rescue media" support reading a tibx file located on a Bitlocker-encrypted drive ?
From the answer above, I understand it's not the case for TI2020 and you need to build a custom rescue media (which is not user-friendly).
Is it still the case with TI2021 ?

If you create the 'Simple' version of the ATI 2021 rescue media, and do this on Windows 10 Pro which has BitLocker support, then this is included in the rescue media but there are some steps that are needed in order to access a BitLocker encrypted drive in the rescue environment.
When you boot into the rescue environment, you will see a black Command prompt window along with the main ATI 2021 application window. You need to close the ATI 2021 window in order to have access to the command prompt in the black window.
Now, you can use the BitLocker commands to identify and unlock your encrypted drive before relaunching the ATI 2021 application again using "X:\Program Files\Acronis\TrueImageHome\trueimage_starter.exe"
See the following data captured from my own system booted from the ATI 2021 Simple rescue media with an encrypted drive connected.

Thanks a lot for these explanations, Steve !
Indeed, the command
manage-bde -unlock B: -password
allowed me to access the Bitlocked drive, using the ATI 2020 boot media.
I would have preferred getting a popup in the ATI GUI allowing me to enter the Bitlocker password, but I can deal with it.
The day I'll need to restore using the boot media, I guess I'll need to recheck this forum to remind the command, but at least I know it's feasible :-)
