OS partition ( C: ) is BitLocker encrypted. I made an image backup of OS + 3 other partitions necessary to Windows (EFI System, MSR, and WinRE Recovery).
During the backup task, OS was in unlocked state.
Afterwards, BitLocker encryption was removed. Later on, BL encryption was applied again, new keys were generated.
Let's say I need to restore the original image to same disk.
My understanding is that, if Rescue Media has BL support and OS is in unlocked state during restore, then the image will be restored and encrypted on the fly (with current
key, not the old one).
On the other hand, if the target partition is not
unlocked during restore, or there is no BL support in Rescue Media, then OS is going to be restored but not encrypted at all.
In any case, I will never need again the old password and keys that were in use when the OS was backed up originally.
Have I understood it correctly?
