I made the error of switching from "Discrete TPM 1.2 to Firmware TPM 2.0 in order to upgrade my Windows 10 Pro to W11. Foolishly I ignored the warning given by the BIOS configuration.
"Intel PTT is a hardware TPM 2.0 implementation integrated in Intel ME/CSME/TXE for credential storage and key management. The firmware TPM key will be stored in Intel ME data region once you enable Intel PTT and Windows BitLocker for drive encryption. Please note that when the recovery key is lost or when the BIOS ROM chip is replaced, the system will not boot into the operating system and the data will stay encrypted and cannot be restored."
I now find that I cannot restore from any of my "Acronis" backup image files to a specific "system" target drive. Acronis tells me that "even though I can complete a restore function from any particular image file, it will not boot from the target restore drive" .
I read about a "key" to unlock the volume on which the image file was saved, but I never wrote down any key. I was also never given the opportunity to find, read or record a key.
In all other ways all my hard drives are accessible when operating normally under Windows 10 Pro. Bitlocker IS NOT activated for any of my drives
The problem is I have lost restore functionality to a system target drive of my backup Acronis images. This also applies to any new Acronis backup images.
My mother board is an ASUS ROC Strix Z370E.
I returned my BIOS setting to Discrete TMP 1.2, but of course to no avail as the impact on Acronis Recovery function appears to be permanent.
If all else fails can I reformat my "system" drive and re install Windows to reset Acronis Image functionality to normal.
Is there some way that I can retrieve the KEY from the INTEL partition, even though Bitlocker was never activated?
