Hey guys, I got a MacBook Pro Retina 15'' with 256GB of SSD. I got Windows 7 installed via Bootcamp, but now I want to upgrade to Windows 8 (because it scales much better, and it is faster though). Does someone know how to upgrade from Windows 7 to Windows 8 through bootcamp? What do I have to do? - Do I have to reinstall my Windows completely, or can I just upgrade? And are the Bootcamp drivers from Apple updated for Windows 8? Many thanks!
