I am looking at all these dual bios options on motherboards and I would like to know if my motherboard has that or something else to prevent it from being bricked, or is there any other way that I could safely update bios. I heard people make backups but I dont understand how exactly because if the motherboard is bricked you cant go to bios and choose to update to this certain version of bios the pc has to get this information without going to bios.

I want to update bios as I am using a ryzen 5 chip and I got a 2.1 updated motherboard x370 killer.

All these bricking stories freaked me out like articles says there has to be a reason for it to fail like loose connection or bad psu and I never lose power randomly but all these forum posts dont specify any specific reason why it failed.

I really just want a safety net. I just updated my old bios using this psu as well a few days ago without a problem (but I didnt mind risking it as it was a 6years old mobo).

Best way to do it is put the bios file on a fat32 formatted USB stick, boot to the bios and use the tool built into the bios to do it.

I'm not sure what ASRock call their tool, but asus call it ez flash, gigabyte is q flash, and msi is M flash.

Load bios defaults first, save and exit then reboot back to the bios and flash, never flash with overclocked settings on your cpu or ram regardless of how stable you think it is.

Failing that, you will have to use a dos bootable USB stick which you can create easily with rufus, and add the bios files, then flash in dos mode with a command.

If you follow all of those instructions and the board dies, it's not your fault, rma the board, however, some newer boards come with a feature called...
