Clover Can't Find USB?

I've been following this guide to try and hackintosh my T420. I successfully created an install media, but I still need to change the EFI with clover. I've got Sierra in a VM through VMware, and the mac recognizes it, but Clover doesn't. It only lets me install to my EFI for the VM, not the USB. Clover Customizer the EFI folder too, but when I open it from Clover Customizer, the folder is empty. How can I get Clover to modify the EFI for the bootable USB>
