    Move system partition to system reserve partition


    I had just install a new m.2 NVMe card yesterday and had cloned my primary drive over to the m.2. It was working wonderfully and was booting up okay then I had decided to clear the original primary drive. I had then tried updating windows from settings and when it tried to boot up I got an error saying bootmgr was missing. I had reinstalled windows with the media creation tool back onto the original drive after it wouldn't let me install onto the m.2. I now boot from the original drive then it goes to a screen saying there are two volumes that retain a copy of windows. I select the first one and I notice Its running from my m.2 as per the image. It shows boot and is the C: drive but the other disk that i boot from still says system in the partition.

    I would like to know how I can safely move the system partition over to my m.2 and boot from it without it asking for a volume to select when starting. Please and thank you!Move system partition to system reserve partition-annotation-2020-12-02-162815.png

    In a command prompt with admin privileges:

    diskpart
    select vol h
    active
    exit
    bcdboot C:\Windows /s H: /f BIOS
    exit

    However, your system BIOS must support booting from NVMe, and since you are booting in Legacy BIOS mode and not UEFI, it is pretty doubtful that it does. Since you have not provided any specs at all regarding your computer, we cannot say for sure if your computer supports booting from NVMe or not.

    My apologies. I had filled in some info that I think may be useful. I can't find anything that says it can't boot from NVMe so Im a bit hopeful but If thats the case then at least I know theres a way to fix it.

    I had read somewhere that said x4 x4 for other m.2 and i was looking around in my bios and saw my m.2 was set to x16. I switched it to x4 x4 x4 x4 and restarted it. Not really sure what it meant though. Bam booted right up directly into the os from the m.2 ssd. Thank you! Hope this helps anyone else that had a similar issue if by chance im not the only one.
