New Build Boot Issues

post #1 of 6
Thread Starter 
Hey guys,

So I have a new desktop build i'm working on and it seems I've run into some trouble. When I go to boot, Dr. Debug seems to throw up an "A2" error. I don't have any IDE devices installed so I'm not 100% sure why this is occurring. Anyways, the build boots to the BIOS and ASrock utilities but when I go to boot to Windows 7, it seems to not read anything. It just says "Press any Button to read media device". I've tried three different Digital River .ISO's and (obviously) three different DVD's. I've heard issues about the dreaded "A2" error and the mobo's then subsequent inability to boot to ANYTHING but what is strange is that as soon as I put a BackTrack (Linux) Live CD in, the device boots to BackTrack. I am guessing this rules out any hardware issues as once it does boot, the A2 error disappears and I get a blank Dr Debug screen.

Could it be the DVD's I am using? They are Verbatim DL DVD-RW's. My Optical Drive is an ASUS Blu-Ray Multi-Drive.

Could it be that I am burning the .ISO incorrectly? I am just finding the downloaded .ISO file, right clicking and then clicking "BURN". I am on a Mac and I am not familiar at all with it's burning utilities, etc. If I was on a PC this wouldn't be a question. (Unfortunately). Is there a certain application I should be using to create a LIVE Windows 7 ISO?

Is it in AHCI mode? Also try resetting CMOS (not using button on rear I/O, do a proper reset)

How would I find if it's in AHCI mode? I have the ASrock Z77 Extreme 6. I will pull the CMOS battery soon as I get home.

It's a BIOS setting. Not sure where it is on that particular motherboard, but usually you just choose between IDE and AHCI.

If it wasn't in the correct mode, wouldn't it have never booted the Live CD ?

I honestly don't know what the difference is, I just know it can cause weird problems sometimes so it's worth trying.
