Win 10 Bitlocker, TPM, UEFI BIOS Recovery problems
Hi all,
I am testing with Acronis to see if it works at all with Bitlocker on our machines. We have Bitlocker and TPM enabled in Windows 10 with a UEFI BIOS. Acronis can't clone the disc, it says to create a Bootable media disc. I did that and backed up the drive to another drive in the machine. When using the bootable media I select 64 bit or 32 and it goes to the black screen "Acronis Loading" then it just goes black. What is the issue here?

Hi Steve.
Acronis is copatible with Bitlocker only if you backup disk without OS on it.
I have made many tests and Acronis cannot restore the system disk with one partition on it and encrypted by bitlocker (windows 10)
I took pc with one drive, install Win10 Ent to disk and encrypt disk C with bitlocker.Then I enable Suspend protection for bitlocker and made the backup of whole disk to Acronis cloud. At this time a can I still take this disk and decrypt it on another PC. I use the same hardware for restore (made fdsik - clear for disk to destroy all partitions on it) I boot form Acronis bootable media and restore whole disk with all partitions.
And after that I have no bootable system - BSOD unmountable_boot_volume. And this is expected because disk shown as encrypted. But now you cant decrypt this disk on other PC (before its was ok), you will get an error - "The Bitlocker encryption on this drive isn't compatible with the version of windows. Try opening the drive using newer a version of windows"

Evgeny, welcome to these user forums.
The key statement from Acronis is that it can only work successfully on BitLocker protected systems when that encryption is transparent and appears to be unencrypted to the Acronis application. This is why any backup made with ATIH does not include any BitLocker encryption in the resulting backup image file and BitLocker would need to be reactivated again after the image is restored back again.
See KB document: 56619: Acronis True Image 2016: Compatibility with BitLocker for the official statement on this matter.

Hi Steve,
We have made some tests and got this resaults - If I make disk backup (win10 with bitlocker) from booted system to network share or to the second hdd - restore works fine and I got a working system without bitlocker.
But if I make the same backup to the Acronis Cloud and try to restore it- I get the errors I wrote above - BSOD unmountable_boot_volume and strange bitlocker on disk.

Evgeny, thank you for the update and results of your testing of backups.
I would recommend raising the issue of the failed restore from the Acronis Cloud as a Support Case directly with Acronis Support as, to my mind, there should be no difference in the results whether restoring a full backup from a local / network location or from the Cloud.
