Ok, I've just spent the last 5 hours of my life pulling my hair out just getting Windows to install on my brand new rMBP. All the USB drives I tried kept giving me the "no bootable device" error. Finally I plugged in an external DVD drive and used a Windows 7 DVD and it installed just fine. Now my problem is the Bootcamp drivers are not installed on Windows, and there are no USB drivers so Windows won't even detect my usb drive that has the drivers on it. I can't copy the drivers to the windows partition from within OSX because it's NTFS. So what do I do now? How do I get the drivers onto Windows without any USB drivers already installed? I'm really confused here.
