    Convert MBR to GPT - MBR2GPT fails with error 0x00000000

    I've been trying to convert my OS drive from MBR to GPT for 3 days so I can enable secure boot. OS is windows 10 Pro, 21H2. Laptop is a Samsung NP930X5J. Original SSD was 256 GB; I imaged it to a 1TB SSD many years ago using Acronis, replicating the whole disk (4 partitions), expanding the main partition to fill the larger SSD. System has been working trouble-free for ~8 years. Original system was Windows 8.1 pro, upgraded to Windows 10 pro a long time ago. No dual-boot, nothing fancy at all. When I first ran the following command: mbr2gpt /validate /allowOSfull I got "Disk layout validation failed for disk 0". After days of experimenting, I eliminated one of the 4 partitions (a 100MB partition that had virtually nothing in it) and after that, I was able to get a 'validation completed successfully'. So then I tried mbr2gpt /convert /allowfullOS. The command failed with this error: Code:
    System boots fine into Windows 10 in this configuration; I just can't convert to GPT. I'm now heading down the rabbit-hole of pursuing the 0x00000000 error, but would appreciate any insight from anyone out there! Thanks.

    Issue Converting SSD from MBR to GPT

    Hi everyone, and hope you are all having a good day.

    I have a Dell Laptop which I recently installed a Kingston SSD into. I've been trying to change the drive from MBR to GPT for a few days now, and nothing seems to be working. I've tried running the command multiple times with administrator permissions "mbr2gpt /convert /allowfullOS", and this is what it always spits out:

    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

    Cannot create EFI system partition. Error: 0x000036B7

    MBR2GPT-undo: Extending back the OS partition

    MBR2GPT: Conversion failed

    Nothing seems to work. All other third-party programs I've seen people use (like EaseUS) won't let me use their tools without paying for a license. Any help would be appreciated. Thanks!

    When I try to convert MBR2GPT it gives me an error code "0x000036B7"

    MBR2GPT fails to convert to GPT despite resizing partitions.

    Shutdown and detach all other drives (SATA or power cable)
    As @SIW2 suggested, boot from a Win 10 installation drive, launch a CMD window (Shift+F10) and run:
    MBR2GPT /validate

    and

    MBR2GPT /convert
