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 126.96.36.199.0 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?
