Cannot reinstall from usb

I had high Sierra installed and went to go reboot and now the clover logo appears without showing drives or options. So I went ahead and created a Mojave’s usb installer using Unibeast and I’m getting the same issue. Why won’t any of the clover drives or usb installer options show up ? Ps I detached the ssd that Sierra was installed under too
