After finished building my pc, I tried enter the bios, and it's different from what i was expecting, you could only read "msi click 5", two empty tabs called "boost" and "a-xmp", in the right "cpu speed" and "ddr speed", and under an empty box with the label "boot priority", and nothing else. I have a b450 tomahawk with a ryzen 5 2600x, I already installed windows 10, but I don't know what to do about the bios.

ps: when I try to go in the boot menu, i only get a "arsenal gaming conquer the battlefield" box, with no option, nothing.

pps: I found an image that shows exactly what I see
