Hello all, So I finally got my rMBP after a 5 week wait and it is an amazing machine. When I tried to install Windows, however, I ran into a big problem. I can't even get to the windows installer! I tried Windows 7 and Windows 8, both via Boot camp assistent to my USB Flash Drive. Neither of them can open the setup. Instead I just get a Black screen. That's it. No flashing underscores, just a black screen. And nothing happens. When I boot the EFI loader from the windows 8 disk I can actually launch windows setup, but it puts ALL my devices (SSD, and 2 connected USB devices) on a single disk called DISK0. Windows won't install on any of the partitions and just comes up with an: "Partition table isn't GPT" error. Weird, because the partition table is in fact GPT. Anyone ran into similar issues with the rMBP? Should I get a replacement? I really need windows to work for some programs. And I do really need to bootcamp in to windows. Thanks for the thoughts.
