Hello everyone, I have been researching this and so far cannot find an answer.
I recently bought a new rig: OCZ SSD, ASUS sabertooth p67 mobo, intel i5 processor, and 2 120 gb sata drives.
The problem is that I cannot get the PC to boot to SSD if the satas are plugged in. I have tried installing to the SSD without the SATAs plugged in, and then plugging in the SATAa after everything worked. When I did this the PC wouldn't boot (Just a blank screen: though the SSD still appeared as a boot option in BIOS). I tried changing the SATA ports to raid, AHCI, and IDE and that still didn't help.
Then I tried installing the OS with all drives plugged in. The SSD was in AHCI mode and the 2 SATAs were in raid mode. Everything installed fine, but the system gives me a 0xc000000d error and fails to boot (did not get this error in the above setup).
