    Can't Boot from Samsung 960 EVO M.2 Drive, Sort Of


    installed W10 on the above drive. When I try to boot from it, it doesn't work. It says insert boot media. I had already installed W10 on the drive. And I can see the drive in BIOS and windows explorer when booting from another drive.

    Oddly, when I boot from an SSD drive also connected, that works, but it asks if I want to use W10 on Volume 4 or 7. When I choose 4, the Samsung M.2 drive does indeed boot.

    Anyone know what is going on? Obviously I want to boot from the M.2 without needing another boot drive.

    Thanks.

    CPU - i7 6700K
    Board - Z170A M3 Gaming
    RAM - G.SKILL TridentZ Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM
    OS - Windows 10 Pro
    GPU - none
    Sound Card - None

    Make sure to change the boot order in BIOS so that the 960 is listed first.

    Have you installed Samsung's NVMe driver?

    The problem is that the OP installed Windows onto the second SSD while the first SSD was still connected. Instead of putting separate boot files on the second SSD, it set up dual booting off the first SSD.

    Thanks for making that concise Navy. It I were faced with that situation I would unplug the first SSD, install Windows on to the new 960 then plug the old SSD back in and format it (after backing up any personal files).

    feeling dumb. looks like I didn't disconnect all other drives when installing. Never had that problem before. Anyway, thanks much.

    np, its best to unplug any secondary drives if you're doing a clean install.

    All you have to do is shrink the OS partition by 100 MB, create an EFI System partition, and use the bcdboot command to put the boot files on it.
