So get on a computer that is working with windows or Mac OS and plug in your USB and open up the file Called efi then go to clover >driversUEFI it might say 64 at the end depending on your system open it and see if you have a file called osxaptiofixdrv-64.efi.
If you don't download it from here
Or look it up it should not be to hard to find
Then boot off the drive preferably in 3.0
Also try the preset flags and if it does not work add the nvidia flag
