I was not able to run Boot Camp setup directly. I downloaded Boot Camp Support Software and extracted the contents. I don't need Boot Camp to help me boot, I just need the drivers to get things like the keyboard, trackpad, and wifi adapter functioning properly. However, I can't seem to get the Boot Camp drivers to install properly. I'm not having any problems in booting Windows 8 or using it. I have a MacBook Air 2013 that does not have MacOS installed, but is booting Windows 8 Pro 64-bit (clean install, not upgraded from Windows 7) in a vhdx file via EFI.
