@george1421 Update.

So we did some more testing and it turns out that the Intel Volume Management Device setting in our system BIOS is whats causing the issue with our NVMe drive. We found this because even after getting FOG to successfully push an image to the drive, Windows was unable to boot from it. We disabled the VMD setting and the PCI device is no longer addressed on an extended root hub and Windows booted normally, so we tested this with the orignal bzImage as well and it all still works as expected.

I had a similar issue, but (dumb) lucked into a solution.

Dell Optiplex 3040, BIOS set for UEFI: Onboard NIC (IPv4) first, Windows Boot Manager second.

Installed Win10 Enterprise from USB. After the install and first time on the desktop, before installing anything else, a reboot would come out of the UEFI network boot with Preparing for Automatic Repair. (I gave it plenty of time — about 14 hours! — never got past that screen.) I installed again and got the same results.

I made one change in the BIOS: added a check to ‘Enable Attempt Legacy Boot’ and then installed again. This time, at the first reboot, the screen went dark and … nothing. Manually powered off and back on and was able to log into Windows. But the next reboot, again the screen went dark and stayed that way. So I removed the check from ‘Enable Attempt Legacy Boot’ and now Win10 is working fine, normal reboots, exiting from the UEFI network boot into Windows.

Hope that might be helpful to someone.
