I am trying to upgrad a 500GB SATA disk that was bitlocker encrypted to a 2TB disk. Here's what I have done so far. 1. Turn off bitlocker on the source disk. This was necessary to be able to expand the partition on the target disk. A bitlocked partition apparently can't be expanded. 2. Used EaseUS Partition Master to migrate the OS to the new disk. I tried using Clonezilla but could not get the resulting disk to boot. (bcdboot did not help) Many hours later I have the new disk installed, booting up, and mounting as C: But when I try to restart Bitlocker I get the following message,
This device can't use a Trusted Platform Module. Your administrator must set the "Allow Bitlocker without a compatible TPM" option in the "Require additional authentication at startup" policy for OS volumes.
The system does have a TPM v 1.2 and it is initialized. The TPM management plugin reports that "The TPM is ready for use."
Am I going to have to re-initialize my TPM?
