   HI ! 
(sorry for my english)
my motherboard : Extreme6 x99 with last bios from internet flash. 
CPU: i7 5930k
ram: 48gb  / 4x4gb + 4x8gb ..so all ram slot is full
PCIE 2,3,4,5 are empty 

I have a new Samsung 960 pro and is working under windows like secondary ssd at the moment.
so i wish install win10 on.

I made a GPT+UEFI win10 usb and i install the win10 on 960 pro ! (unplug all sata before )
after install i change back to CSM in bios and choose Samsung960 pro to priority boot.

but when i restart my pc  i have a error  "Reboot and Select proper Boot device "  

How is possible boot from 960 pro ? 
is working secondary ssd and show in bios but cant boot ?
need a new nvme driver to integrate in win10 usb key ?

or can you make a firmware update ? PLEASE !!!

thank you!
from Hungary :D

	IF you Install your Windows 10 On a GPT UEFI Harddrive you cannot boot with it when you activate Legacy Bios (CSM) Also under Win10 CSM should not be needed
