    Your EFI partition should be Active & Boot - is all column text visible?
    Allocate your Windows partition a drive letter. (and name).

    I have assigned the letter C and labeled it WINDOWS.
    It only says Active though. Nothing says Active & Boot

    Should I do another clean install to make sure that EFI partition says Active & Boot before I replace the working C drive with my old non working windows?


    EDIT
    I opened AOMEI Partition assistant professional edition while waiting. In this program the status only says Boot and not Active

    The partition type is set wrong for C:\Windows. It should not be set as an EFI partition. You need to change the partition ID, probably using diskpart.

    The FAT32 partition on disk 1 should be the only EFI partition.

    The commands should be:

    diskpart
    list disk
    select disk # <replace # with the number of the disk we need
    list part
    select part # <replace # with the C:\Windows partition number
    set id=ebd0a0a2-b9e5-4433-87c0-68b6b72699c7 override
    exit
    exit

    After you've sorted out the partition type (thanks @NavyLCDR), running Startup Repair or Macrium's Fix boot should do the rest- I hope.

    Do you know what, I'm currently loving the two of you forever.
    I'm now using my old windows installation. Everything is still here and seem to be working just fine.

    Now I just need to do these same stages once more so that I can get everything over on the SSD I used to have it on.
    After that I'll take an ISO image of the entire disk so that I just have to load that onto the disk.

    By the way, could it be that I only need to change the type on my former main SSD to fix the problem on by running startup repair from Macriums fixboot?


    No matter what. Thank you so much for all the help.

    Yes. Post a screenshot of AEOMI Partition Assistant or Minitool Partition Manager display of it and we can see if there is anything wrong with it.

    Is that also UEFI - you mentioned one was MBR?

    Note: make sure that having been inducted into disk imaging, you now use it routinely to maintain periodically updated image sets for every disk you have. Macrium's option Backup, Windows Backup, will select all partitions needed for Windows.

    Once you have those, you've a good chance of recovering easily from ransomware, disk failure, user error, cosmic rays, alien invasion.... (well, not the last, but you get the idea) - and having a second chance- relatively quickly, without technical help.

    @dalchine
    The MBR disk I was talking about was the secondary SSD which I now did the clean instal of GPT/UEFI windows 10 on to fix the entire issue. So I have no MBR disk at the moment.

    From what I can see myself. It's missing the FAT32 EFI system partition that is suppose to help it boot.
    There's only 3 partitions instead of 4, which is the normal.
    It's seems, what ever caused this merged the two partitions together which removed the boot in the process.

    I think the best is to do another clean install on this one, replace the C drive with the old one, set the correct partition type with diskpart and then run the startup repair from the Macrium Reflect.

    Unless there;s some kinda easy way to just add that partition.
