Bitlocker on Windows 2022 cant encrypt OS Drive

I'm installing Windows Server 2022 standard with clean install. It has two hard drives. I can encrypt a drive if it doesn't contain the operating system, but I can't encrypt the drive where windows is installed. When I try to "Turn on bitlocker", it reports: "The requested operation is not supported". Can someone advise me on why this might be happening?

 

Thanks in advance!

    Sorry for asking a perhaps obvious question, the system does have a TPM chip? If not, then you could encrypt it but use a USB as unlock?

      Hi Harm_Veenstra ,

      Yes. My device manager shows TPM 2.0 working normally. Oddly enough, I did a clean install of Server 2019 and it works fine. It makes me suspect there is something going on with Server 2022.

      I appreciate you responding. Thank you!

        Just added a virtual TPM to my Windows 2022 server and encrypted my OS disk C:\, the D:\ drive can also be encrypted but as a Bitlocker To Go disk. I had to install the Bitlocker Drive Encryption Feature of course, but pretty straight forward.. Not sure what's going on with your system?
