Some things to note, if I disconnect the HDD and the DVD drive, and have a bootable OS installed on the SSD, it boots fine from the SSD immediately. But as soon as I add the HDD or DVD, it doesn't boot from anything and goes straight to the BIOS. Also, if I turn off the PC and disconnect the AC power and plug it back in, it seems to boot fine for that one time (follows the boot order, not to BIOS unless I hold DEL), which made me think it was the fast boot setting throwing it off (since it's set to do normal boot after AC power loss). Tried turning off fast boot with the same results (boots to BIOS and have to select device).
Any advice would be greatly appreciated, I've gone through ASUS support and he's recommending me one thing a night via email and has come back to asking me if I have the boot order set correctly in the Advanced Mode BIOS. Could it be a bad board and should I RMA? Could it be that my DVD drive and HDD are older (purchased in 2009)? Or is it just a BIOS setting I'm not catching?
Which SATA ports are your devices plugged into?
When you say you have your boot order set, I'm assuming you've set it to boot from Hard Disk and then DVD, and then specifically set the order of which Hard Disk to use (read: It tries booting from the SSD first and then the HDD)?
I looked up your 750GB HDD and it supports AHCI, so that's not an issue,
Are you running the most recent BIOS? (1708)
I've had some of my USB devices interfere with booting when I was first setting up my Sabertooth. On a whim, does booting only with a keyboard plugged in make any difference?
