    Need Help with MBR2GPT


    Hello,
    I'm running ver 2004 in legacy BIOS mode & trying to move to UEFI
    The \validate completed OK once I reduced MBR partitions to 3 (from 4). Then ran the \ convert and got the following:

    MBR2GPT: Attempting to convert disk 0
    MBR2GPT: Retrieving layout of disk
    MBR2GPT: Validating layout, disk sector size is: 512 bytes
    MBR2GPT: Trying to shrink the OS partition
    MBR2GPT: Creating the EFI system partition
    MBR2GPT: Installing the new boot files
    MBR2GPT: Performing the layout conversion
    MBR2GPT: Migrating default boot entry
    MBR2GPT: Adding recovery boot entry
    MBR2GPT: Fixing drive letter mapping
    MBR2GPT: Conversion completed successfully
    Call WinReReapir to repair WinRE
    MBR2GPT: Failed to update ReAgent.xml, please try to manually disable and enable WinRE.
    MBR2GPT: Before the new system can boot properly you need to switch the firmware to boot to UEFI mode!
    PS C:\WINDOWS\system32>

    I'm lost as to what I should do next? Any help would be appreciated.
    Best,
    Mike

    Your computer is already booting in UEFI mode which means the drive is probably already in GPT format. What makes you think it isn't?

    What does diskpart, list disk show?
