So I've managed to install Windows 8 on my new rMBP, using bootcamp. But when you get to the first screen where you are suppose too customize Windows 8, I have no mouse or keyboard working. So i can't do anything... I have tried connecting a external mouse, and a external keyboard. But none of them works either. They both work fine during the installation process, but after it restarts and you get to the customize screen to setup the computer it stops working. It seems many have this issue but I can't find any solutions to it. I would LOVE some help with this, I've tried reinstalling Windows 4 times now, with external CD and USB. *Edit* Seems like many are having this issue. If you are, this is how you resolve it. USE A USB 2 DRIVE! And then follow these stepps: 1) Fix a Windows 8 or Windows 7 .iso, this procedure fixes the mouse issues both have. 2) start bootcamp and when it asks you what you want to do, check the first two options (create windows 7/8 install disk and download support media) let it work...once it is done then quit bootcamp COMPLETELY. 3) start bootcamp again and this time select install support media to the same usb drive let it work and then quit bootcamp COMPLETELY. 4) start bootcamp and this time select install windows 7/8. bootcamp will automatically restart your computer into windows setup. From there continue on like normal. you have to let bootcamp restart your computer (you can't close bootcamp and then restart from the menu yourself...you must let bootcamp do the restart) your usb drive shouldn't come out of your computer during any of these steps.
