    Cannot get Bitlocker to..work


    Hi all.
    This is a new modern system with an Asus Z790 motherboard.
    I have several m.2 drives and one of them is the OS disk. See attached on the layout.

    I imaged the system from the previous computer which was very old (BIOS) and restored it to the new system and it works just fine.

    However, I am unable to get Bitlocker to work as I get the error "Changes made to your computer require that you restart before running BitLocker Setup."

    This is running Windows 10 22H2 + all updates. Any ideas where to go from here or what needs to be done to get it going? It shouldn't make any difference but the m.2 drives are Samsung 980 PRO SSD w/Heatsink.

    I do have dynamic disks as RAID0 but this is not the one I am trying to encrypt. Only the OS drive is what I want to encrypt. If I encrypt any other basic disk, it seems fine no problems.

    Thoughts?

    Note that BitLocker isn't available on Windows 10 Home edition.

    You have a new computer with UEFI BIOS but your Windows drive is set as Legacy-MBR. You should convert it to UEFI-GPT. Win 10 has an app to do it.
    Convert Windows 10 from Legacy BIOS to UEFI without Data Loss.

    Why do you only want to Bitlock OS drive?

    The primary purpose of Bitlocker is to protect data.
