Optiplex 790 boot issues

So I've been using a VM of mojave to build my bootable USB for my Hackintosh build. I've made and remade it about 10 times and can't get my optiplex to boot from USB. I've used legacy and UEFI and used unibeast and clover seperately without any luck. Any suggestions or help?
