    Why does MBR2GPT say I have 4 partitions when I only have 2?


    I'm trying to convert my MBR drive to GPT, but every time I try it doesn't work, and when I look at the report in the windows folder it says I have 4 partitions, when I only have 2 in the drive I am trying to convert. Is there any way to fix this?

    :)

    I also think so.

    Windows upgrade 1903 automatically created a 450 mb recovery partition which I had to delete as mbr2gpt don't work with more than 3 primary partition.

    So, do I need to create a recovery partition now to get mbr2gpt work?

    I have already tried what you told. It says something like "can't enable win re service "

    mbr2gpt error: Unrecognized partition found, index 2

    Thank you both for your suggestions. Unfortunately, before I could start, my pc quit booting, showing a NTFS file system error.

    Any idea why disk manager shows 3 partitions and mbr2gpt shows 4?

    Thanks again, will repost when/if I am ever successful.

    Welcome to the Forum

    On disk 1 you have 4 partitions
    Partition 0 and partition 3 are unknown type (probably from Linux)
    Boot from the rescue disk and run MiniTool partition to see what you have on them. (Windows disk manger doesn't show Linux partitions)

    You only use mbr2gpt to convert a Windows boot able Legacy-MBR drive into a UEFI-GPT.
    So you can only apply mbr2gpt to drive 1. Your BIOS MUST be able to boot as UEFI-GPT.

    To convert Disk 0 and Disk 2 my suggestion is to use MiniTool Partition Wizard (Is also on the rescue disk)

    This is what I would do:
    Make a Kyhi rescue disk . Download the iso file, format a 2G USB flash drive as Fat32, make the partition active, mount the iso and copy all files and folders to the 2G USB flash drive.

    Detach disk 0 and disk 2 from the MB (SATA or Power cable)
    Boot from rescue disk as UEFI and with MiniTool partition delete partition 0 and partition 3.
    Convert drive 1 to UEFI-GPT using Brink tutorial
    (open a CMD window and type: mbr2gpt /convert)

    Any change in partition is a risky task. Make sure you have all your data baked up on another drive. Better make a drive 1 image using Macrium Reflect (also on the rescue disk)
