Product: Z240 workstation
Operating System: Microsoft Windows 7 (64-bit)
I can't get new Z240 workstation to boot into WinPE on Windows 7 x64, Windows 8.1 x64 and Windows 10 x64 with only and NVMe drive installed to the M.2 slot on the MB. I've tried plain OEM Media and WDS with WinPE with different drivers added to the boot.wim file, all no luck.
It seems there must be some sort of bug relating to the Samsung 950 pro M.2 NVMe 256GB drive I'm using. When I leave this as the only drive (+CDRW), the computer always hangs as soon as WinPE starts. If I leave the Samsung NVMe drive installed and add another SATA drive such as a Samsung Pro 850 SSD, it behaves fine- WinPE then loads and I can see both drives.
I was able to install Windows 7 on the NVMe drive and booted into Win7 as long as the SATA drive was present. As soon as I removed the SATA drive and it starts loading windows 7, it immediately hangs again.
It shouldn't be NVMe driver support as Windows 10 WinPE has native NVMe support and has the same problem, so it must be something else. I suspect it's either something I have to turn off in the BIOS or some other BIOS/UEFI bug.
