System cannot find any bootable devices

[Corndawg]

I've got an Asus x570 tuf wifi Mobo with a R7 3700x. I just tried updating my bios to 1405. Everything went fine updating but now I'm stuck in bios. My two drives (500GB Samsung SSD boot drive and 5TB HDD) are recognized and show up in AHCI but won't show up in my boot settings.

 

When I go to boot settings I also get an error saying "the system cannot find any bootable devices."

 

I can still get in and see all my folders inside my drives, I just don't understand why it doesn't recognize my drives as bootable

Can you change your boot mode from AHCI  to something else?

Struggling to find the settings to change that. Any idea where that is?

Not sure if this is the right solution, but I enabled csm and it booted right up after saving the bios settings. I'll keep checking back though cause I'm not too familiar with getting these settings right
