Bios help, I'm stuck

[thattoe]

So, I believe that I have Award BIOSversion F5. I can't confirm due to my current predicament. I had selected "Load optimized Bios options" or something similar to that. Then I rebooted, and now I'm stuck. On reboot, I get a flash of the bios logo picture (the one where it gives options like pressing "del" for the main bios options). No matter what key I press, I can't seem to get it to go into the bios. 

Then it loads a page that says:

Serial ATA AHCI BIOS, Version iSrc 1.20E
Copyright © 2003-2008 Intel Corporation                                              23
** This version supports only Hard Disk and CDROM drives **
Please wait. This will take a few seconds.

Controller Bus#00, Device#1F, Function#02: 06 Ports, 04 Devices
_

And, I wait several hundred seconds (even half an hour), with just a flashing _ . I cant type anything or seem to get any response. The 23 doesn't count down, and my keyboard worked fine before. I've disconnected and reconnected it to no avail.

If I could simply get back to the BIOS menu, I could undo my optimized option.

Currently running Windows 10, though I don't know if that applies to this situation.

It seems to freeze only when there's one particular hdd connected to it. It is the hdd that had Windows 10 on it. My 2 other hdds allow me to continue past this point. Is there any way to get past this error, without wiping the hdd clean?
