Cant reach Sierra installer

After trying to install high Sierra and failing due to clover not showing the installer, I decided to install Sierra. I made a unibeast USB using a (terrible) virtual machine then added a Ethernet kext and multi beast in a new folder on a different USB. When I'm trying to boot it does show up in cover but gives me this error. Any help/suggestions are appreciated.
