That is a really nice guide! Thanks a lot! Since I am really new to this community I have a question. Would this also work with other Graphics cards, say the GTX770, or is this guide specifically for the GTX 970? Also I heard something that the rMBP early 2013 would not be able to install Windows in EFI mode. But the fact that I can select EFI Boot when I have the Windows installation stick plugged in shows that I can indeed install Windows in EFI mode right?
