im trying to install my version on windows 7 64bit home edition via bootcamp. I had my trial of 8 working fine but wanted to put the full version of win 7 I have on it. I followed the exact same process let bootcamp assistant to create the usb boot stick it did that and now its on the partition page. I have selected 200GB for win 7 but when i press install it comes up with "Earlier versions of Windows are not supported. Please use a drive or dvd which contains windows 7 or later" Any ideas why its doing this?
