    Did you make the "C:" drive active first?

    If so, you could try the startup repair without the other disks connected.

    Yea, no, I kept unplugging all of the wrong drives because I thought my m.2 drive was my boot drive, so now that I know it isn't, I have to do a complete wipe and reinstall onto the m.2 drive. Well....I guess I don't have to wipe the drive....is there a way for me to reformat and set up my m.2 drive (disk 3 in the original picture) to be uefi and then transfer over my windows install somehow without having to wipe the drive that was my windows drive?

    If the m.2 is like one of these shown here it is not easily "unpluggable", have to remove a screw to enable it being removed.
    m.2 drive at DuckDuckGo
    I would think being more securely fastened to the motherboard it should be seen as Disk 0 in the BIOS.

    That was my assumption as well, but nonetheless, when i click on disc 3, and go to properties, it reveals itself as my 960 evo. My mushkin eco ssd is disk 0 for some strange reason.

    deadlyvortex,

    If you like, you could try this below to avoid a clean install:

    When you have all disks disconnected other than the M.2, check to make sure the M.2 is selected as your boot drive in your BIOS, and see if a startup repair can repair the boot manager to allow you to boot from the M.2.

    When I disconnect all of the other drives, it can't boot because there are no boot files or system files on teh m.2 drive. I originally botched my windows installation and installed everything on the wrong drive

    The good news is that I can make sure I do it right and with uefi this time though. Thanks for helping me discover the error I made though Brink, I appreciate it!
