I have just updated my bios on an ASUS MB.

Anyway, I set a restore point in Windows BEFORE I flashed the bios.

Can I restore Windows using that restore point now and not have problems?

If you updated the BIOS, that is independent of Windows.  If you do a restore to before the BIOS update it will not do anything since the BIOS is not part of Windows.

On the other hand, if you updated the BIOS and it corrupted the BIOS, unless there is a BIOS recovery on the motherboard or the motherboard vendor (ASUS in this case) has a recovery procedure your motherboard could be Toast. 

Yes, but does not Windows build itself based on the BIOS?

A restore point in Windows is not a restore point for your BIOS too. You have to update/restore your BIOS independantly to Windows.

I re-read my original post and I really don't know how to make it any clearer.
Maybe it's the order that I typed.
How about this.


I created a restore point in Windows for various reasons.
In the interim, after I had created the restore point in Windows I updated my BIOS.
2 separate procedures.


I know they don't have anything to do with each other except for when Windows booted after the BIOS flash, it changed itself because now the BIOS that it uses to access information had changed. This is a normal I pre-sume. I mean, Windows uses the BIOS to run correctly, right? 


Anyway, Now, If I return Windows to the state it was in pre Windows restore point, Windows will not be the same as what it is now because the BIOS is different.


I imagine a simple reboot would clean things up. But, I'm not sure.

The BIOS shouldn't change windows at all. BIOS - Basic Input Output System, does control many I/O functions but the OS is really independent of BIOS changes. I've done many BIOS updates, for myself and clients and it had absolutely no affect on how Windows operated or looked. Windows "uses" the BIOS, the BIOS does not "use" Windows. If you set a system restore point, that should take Windows back to how it was at that restore point, independently of what you did to the BIOS.

I imagine a simple reboot would clean things up. But, I'm not sure.

The BIOS update won't affect rolling back Windows...
BIOS updates are like firmware updates for audio interfaces
Small changes to improve compatibility/etc (not major changes)...

Thanks guys
