    Hello, given that Apple has not upgraded Bootcamp for Windows 8, can I install Windows 7 64-bit now on my just arrived MBP Retina Display 15" and then upgrade to Windows 8 later? Which way of installing Windows 8 has less/no problem?

    My experience in the past has always been that a clean install of the target OS is best, but I've also been reading the w7 -> w8 is pretty painless .... so I think it comes down to need .... how quickly do you need windows up and running ... also if you are upgrading you'll need to have w7 already installed and activated (also "so I've read"). I've been looking for a way to do a clean install with w8 upgrade since I never got w7 and only have vista around which isn't compat with my rmbp

    I've upgraded my *cough* pirated *cough* copy of windows 7 ultimate 64 bit to windows 8 (not pirated) and it went smoothly.

    I'm using an old Mac Mini (early 2009) and it's working great. Just go the upgrade route, it transfers all your files, settings and drivers painlessly. It's much less of a pain in the ass than a clean install of windows and it works just as good.

    I would recommend you a clean install since upgrading from a previous OS would take more space because the upgrade DOES NOT delete the previous Windows folder. Instead, it is renamed to Windows.bak.

    What if we manually delete Windows.bak? Will it still consume more space than a clean install?
