Motherboard won't boot after bios update

Recommended Posts

I just USB flashed my ASRock Z68 bios to 2.10, and although all messages said the update was successful and I can get into the UEFI setup utility, Windows won't actually boot. It just keeps blue-screening saying 'boot device inaccessible'.

 

Any advice would be gratefully received!!!

Try going back to the last working bios - bios updating is over rated

Your bios is probably reset to the factory default settings and messed up the boot order.

Try setting the primary boot device to your windows partition.

I always buy MBs with dual bios. Check if yours have it, then switch to the other bios.

Yeah, I think you have a point when you say bios updating is overrated.

 

Well, sometimes bios updating can help with getting a better overclock or in getting better compatibility with updated processors, etc. 

 

Though the safe rule of course is that if it isn't broken, don't fix it.  =@

BIOS updates are NOT overatted. In fact they are often vital in regard to new platforms. They are also vital to enable support for new CPU's.

 

If you have a new platform with the inevitable issues with a new platform, yes, update.

 

If you are an overclocker and the new BIOS offers increased stability, yes update.

 

In short, if the update has something you need, go for it, if not, don't.

 

BIOS updates are also much,:much safer than they were in the past.

 

MB manufacturers don't go to the trouble of creating a new BIOS for nothing, someone somewhere needs it.

Well, this update has played merry hell with my overclock. Temperatures are going through the roof.

 

Is there any way to revert other than taking the CMOS battery out? Unfortunately ASUS doesn't seem to host legacy bios versions on its website...

Doesn't the update process automatically make a backup of the existing bios in case things go wrong?

Maybe you should decide if you own an ASRock or Asus motherboard first?

You have to go into the BIOS and tell it what is your boot drive.  Look for a Boot tab and go through those options and make sure your primary HDD is shown as the boot drive (the one that has Windows).  BIOS updates are mostly required as they fix bugs.

 

Best regards,
