Hope this helps. Windows 8.1 and Win 10 should load the correct drivers automatically
NOTE: Remove all other drives except optical, check your boot order
When booting from NVMe on my X99 Classified with an Intel 750 PCIe SSD - it took the following steps.
NOTE: You
MUST do ALL 4 Steps - per Intel documents - (step #4 is a head scratcher as to why this needs to be)
1)
Boot Tab ----- Fast boot --- OFF
2)
Boot Tab ----- Boot mode --- UEFI
3)
Boot Tab --- CSM Configuration ---- Launch CSM --- Enabled
a) boot option file ----UEFI
b) Launch storage oprom ---- UEFI
c) Other PCI device ROM priority ---- UEFI
4)
Advance Tab ----- USB Configuration --- Legacy USB Support ---- Disabled
--- XHCI ---- Smart Auto (how mine is set)
NOTE: other items I see in BIOS
Boot Tab --- UEFI Hard Disk Drive BBS Priorities (bottom of page) -- Boot Option #1 --- Windows Boot Manager
Save & Exit Tab Boot Override
UEFI: Built-in EFI Shell
Windows Boot Manager (Intel SSPDEDMW400G4
http://www.intel.com/cont...-drives/000005967.html After setting BIOS --- then I loaded Win 8.1 Pro 64 bit, OS loaded from USB thumb drive.
Upgraded to Win 10 Pro 64bit, activated, then clean install of 10 all from a USB drive
