Try to change Harddrive priority so your raid array is in priority one.
I had trouble with my USB mem ending up Prio 1 so it tried to install on that one.
I gave that a try but it does not help.


Enable RAID, w/ boot rom enabled and 32sec delay, write protection off for now (on later if you need).

In the “SATA Configuration” I have “Configure SATA as” “RAID”. “Hard Disk Write Protect” is set to disable and “SATA Detect Time Out” is 35. That’s it for the RAID options in BIOS.

I have my drives also configured in RAID 0 (Ctrl-I function) in the Intel Matrix Storage Manager Option ROM Utility.

The “Onboard Serial-ATA BOOTROM” that is mentioned in the motherboard manual is not even present anywhere in my BIOS.
