Can't boot into windows, BSOD

[mald]

Hi, today I decided to update my BIOS to the latest version, F6. I currently own a GA-P67A-UD4-B3, which had installed the previous BIOS version, F5. Following this very simple tutorial(http://www.youtube.com/watch?v=DBarcyI7p68) I tried to update my BIOS, but I miserably fail so bad that now I can't get into windows nor not even log into safe mode. Windows repair tool thing came up and restored my system to an earlier version, but I am guessing since the problem is at the BIOS that doesn't do anything. I heard that GIGABYTE motherboards have a dual BIOS and if you screw up one a second one will start up as a backup, is that true? I honestly don't know what to do since this is my first time playing around with the BIOS, anyways if someone could help me it wold be greatly appreciated. I will provide more info if needed, so feel free to ask.

So if I cleat the CMOS my BIOS will go back to default?(which version would it use?) Also how exactly does that second post help me, other than telling me how the Dual-Bios work?

So... should I do this instead of clearing the CMOS? Btw if you would be so kind please answer my previous question, thanks.

Hi mald,

If you want make a clear cmos, read it :

Hi

The first thing to try is to clear the CMOS. Please follow these instructions exactly.

Remove the power cable from the mains supply and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors.

Once done remove the motherboard battery for at least one hour before replacing it.
 
Next plug back into the mains supply and boot.
 
You will now need to enter the BIOS by pressing DEL and load Optimised BIOS Defaults.

Make any other changes to the BIOS settings to suit your self like disabling the floppy drive, disabling the full screen logo and making the HDD the primary boot device and then press F10 to save and exit.

So after a clear cmos, your situation is with Optimisec Bios. Not Default Bios.


EDIT01: Yes before (AND After) change or flash Bios, make a Clear CMOS.

If you clear the CMOS it will just force the system to look for all your hardware again, so if there are any changes or anything is incorrect it should find it then. After clearing the CMOS you then need to load the Optimised BIOS Defaults and then make any other changes that you want to like the boot order etc before pressing F10 to save and exit.

Hope this has cleared things up for you a bit.

Yea, I sort of understand now. Btw how come the dual bios didn't work?

The concept of the Dual BIOS is good but quite often it fails to work automatically and will only do it's stuff when manually prompted. The main thing is that it is there and can be used as a backup to the main BIOS when needed like now.

I solved my problem, and it wasn't as complicated as I thought it would be. Basically the new BIOS update set my SATA Control Mode to IDE, instead of AHCI, and that was giving me a blue screen every time I was about to log-in into windows. I am still not sure why that made a difference.

It isn't unusual at all and it more often happens when someone installs Windows in IDE mode and then finds out that it is better performance wise in AHCI and so just selects that mode in the BIOS. Of course this doesn't work without hacking the registry. It is purely because of the different ways of addressing the data. Anyway at least you have it working again now.

Yea I never messed with my BIOS, I payed NCIX $50 to put my computer together. Btw do you know of any good guides to overclock the i5-2500k on e P67A-UD4-B3 mobo? Thanks.
