Have followed the tutorial opened EFI partition, which was empty to start with, added SINGLE SOCKET EFI folder and contents, rebooted with cmd +r, monitor light changes colour which means it receives signal but screen remains blank, hence unable to continue with the process.Is there a compatibility issue with Radeon cards?
