how to fix curupted bios with Dual bios(no bios switch)

Hello Guys

I've enocuntered problem which i can not solve.

I own a motherboard  gigabyte aorus b450 pro  with dual bios.

I had to update bios cuz USB compability issue.  During update computer froze for about 10 minutes. I had to manually shut down PC and restart. Of course, I fxxked up.  System recognizes the back up bios.  But it resets settings everytime.

It made me wonder if I can fix the main bios some how.  There is no switch on motherboard, I can  not manually flash the main bios.  I tried  also with repowering PSU and hold power bottom .  Is there any other solutions ?

As I've mentioned:  The pc reads Main bios , Coundn't load. Then it enteres to the backup bios of which it not save twak settings.  

Sincerely

Thanks for the response , As I've mentioned they somehow don't have a "bios switch"

But atleast I do have option to boot into windows, Only problem is I want to solve this issue.<fix main bios>

I wanted to update BIOS cuz it supports new ryzen series and USB compabilities issue.

As for now no solution for this issue.

Hi,

If the motherboard is still under guarantee, RMA it.
If the motherboard is not still under guarantee, you can replace the BIOS Chip - it might be faulty.
See: Replacing A BIOS Chip - YouTube 
I am not certain about your exact motherboard but some of my Intel based Asus motherboards have the BIOS chips in a plastic chip mount, the BIOS chips are easily removeable, and you can order new ones.

Bye.
