    I haven't seen much on the web regarding this so for anyone interested in trying this or has any suggestions on what I might look at next, I was able to install/boot Windows 10 on a Samsung 970 Pro NVMe drive in a class Mac Pro, but Windows crashes on subsequent reboots.

    A little background... I have been booting Windows 8.1 for years using a Kingston HyperX AHCI PCIe drive. The "EFI Boot" icon would show up in boot screen. Since macOS Mojave has NVMe boot support, I decided to update boot BOM to 141.0.0.0.0 and install Windows 10.

    I was able to install Windows 10 using USB flash onto a Samsung 970 Pro NVMe drive on a Lycom DT-120 adapter in slot 2. I'm using the GT 120 video card and the installation completes.

    However, every time I reboot, Windows 10 never comes back up fully and reboots midstream boot. It'll do this a few times then come up with the recovery screen.

    Has anyone else achieved a different result?

    GT120 is badly supported with recent W10 drivers, use a know working GPU and remove it from the equation.

    Hey, nice call. Turns out the issue was the GT 120. I can now boot with a flashed GTX 980 and non-flashed GTX 1070. I'm currently troubleshooting an issue where the 1070 loses the HDMI port once I update the NVIDIA graphics driver to version 419.x, but overall, no other issues related to booting via NVMe in Windows 10 on a 2009 Mac Pro flashed to 141.0.0.0.0.

    Thanks again for all your help.

    Nice that you got it working.

    The big problem down the road is with updates, let's se if Microsoft finally got it working. CSM installs and NVMe are even worse, before 1809 + 140.0.0.0.0 I couldn't even get it working like you got it today.

    Would this method work with a Sapphire RX 580? I want a windows 10 installation for gaming.

    Lycom DT-120
    WD - Black SN750 NVMe SSD 500GB

    Not sure if this is the best way to go, just didnt want to waste an SSD on the SATA 2 speeds.
