Question Trouble setting bios/uefi

[Waves100]

I couldn’t get my new mobo to boot for a while, but finally found the uefi/legacy switch on my Radeon xfx rx 480 which got me to a UEFI boot menu.

My ssd was detected but it wasn’t on the boot list, so I started messing around with some advanced boot settings (something that started with a C like CHM enabled?) and there were some boot settings to choose between uefi and legacy, I set those to legacy and now it won’t boot anymore.

I have an asus prime b360m-a, I tried removing the cmos battery for a minute to reset the uefi settings and also tried connecting the CLRTC pins+turning it on and it’s still not booting. Any ideas?

I found a jumper cap and put it on the clearts pins with the power off but the bios still isn’t booting the way it was before I set booting to legacy. Maybe I’m resetting the bios wrong?
