Opencore Help

Hi guys, I am trying to use Opencore to setup Catalina on a X299 system(EVGA X299 Dark) but I am having an issue.
I am following the guide for opencore but when I choose the USB in my bios to boot from I just get the error OC no configuration or something to that nature.
This is my first time trying opencore so I am not sure what I am doing wrong.
