Ga-z97x- gaming 5 bios f6, f7 and f8a , nmve dissapear when i add a sata disk

[Patricio Rosalin]

I have a weird beha viur on the pc. It was runing with 2 sata hdd, and added a new adata xpg6000. At fisrts bios f6 showed , but could not set it to boot. un plugged the 2 data disk, left a win 10 pendrive and nmve disk, installed and booted ok.
Then i add the 2 sata disk, and like it erase the nmve disk and boots from sata. Tried same with f8a. bios.
lloks like when i connect sata disk its overrides and nmve dissapears in bios and also from boot.
tried windows 8-No csm, other os-> uefi, any combination ends the same when i connect the sata ports.
Anyone has idea of bios propper settings to mantain m.2 nmve disk as boot drive?

Finally make it work . Settings:
1: Go to -> Peripherals - SATA Configuration
2: Change 'SATA Mode Selection' to RAID. (M.2 PCIe SSD RAID Mode should be 'enabled' by Default, if not enable it)
3: Go to BIOS Features
4: Set Windows 8 Features to:

Windows 8 Features = Windows 8
CSM Support = Always
Boot Mode Selection = UEFI Only
LAN PXE Boot Option ROM = Enabled/Disabled (your choice)
Storage Boot Option Control = UEFI Only
Other PCI Devices ROM Prioity = UEFI OpROM
On boot choos your nmve with windows loader

Save this BIOS configuration.
