    Problems after convert MBR to GPT


    I was having issues with BSOD while playing games and was recommend to either reset or fresh install. I have a M.2 WD black as my system disk partitioned with one other partition. I have a 500 gig WD blue 2 partitions one for backup\programs and other as downloads and another 250 gig WD SSD green 1 partition used for games. I wanted to use UEFI with GPT has I heard it was better setup. Before I installed win10 I booted to install screen and then used shift+f10 to open command prompt, then used diskpart to convert my M.2 from MBR to GPT then deleted the 2 partitions on system disk and created 2 new partitions, then installed win10.

    After system booted first time I noticed I had lots of other drive letters and when I went to drive properties and tried to populate volumes I noticed things were really screwed up. Using the disk manger my wd green ssd shows 3 partitions and in explorer one of the drive letters shows one of the games I had on my m.2 d:\ My wd blue seems to be fine showing bother partitions and files that were on them.

    Anyway someone could tell me what went wrong?

    The trick is... unhook all the other drives except the one you are installing Windows 10 on.
    After you have Win 10 installed, then you can hook the other drives up again.

    I remember that trick from years ago but being 2021 I figured that would of been solved by now, plus guide I followed never mentioned that.

    Why would my WD green show 3 partitions and games I had on it are gone? Is this problem that serious that it created partitions? I find that hard to believe?

    Well, the easiest way to fix it is to re-install Windows 10 with all the other drives unhooked.
    After the install, THEN we can fix up the other drives.

    Well I figured it out and what happen and reason to d/c drives. When I used disk part to convert it listed my wd green as my disk0 and not my M.2 so I converted it and installed Windows to it.

    Thanks for your help now I understand reasons for disconnecting drives, lesson learned.
