Can’t get past bios

I just built a sick rig but i cannot for the life of me get past the booting. I only have a m.2 970 evo and it shows up in storage into but not in boot priorities even though it was there before but not anymore. I tried to remove it and put it back in that didn’t work. Whatever stuff I touched from the settings I turned back to the default settings. It’s the newest version of Asus bios. I do not have windows yet because I’m going to use the code when I purchase it i don’t know if that’s the issue but can someone please help me??

Core i9, 2070 super sli, 16gb of ram, Asus prime z390a
