Stuck on Apple logo after boot from USB

Following the current tonymac installation guide for Mojave on their customac pro build guide. I'm currently stuck on the apple logo on after selecting boot from USB. It loads two notches on the progress bar then didn't move for 30 minutes. I currently have a bare bones system 1 stick of ram, but I do have my Saphire Radeon graphics card in. Tips?
