Hi there, my friend has just the same iMac as me a week ago (21.5" 2.9-3.6Ghz iMac with the Nvidia GeForce GT 750m) and she is looking to install Windows via Bootcamp to play games. Now I have Windows 8.1 installed via Bootcamp on my iMac, but the price is rather steap at 85 pounds so I've found this copy of Windows 7 Pro on sale on EBay for 25 pounds (link: http://www.ebay.co.uk/itm/Genuine-M...783?pt=LH_DefaultDomain_3&hash=item1c517fb74f). So will this work via Bootcamp on an iMac bought just a few weeks ago? I'm guessing that it will be he saw, process as I had with Win 8.1? And last of all, she doesn't have a SuperDrive, so is she able to download he ISO and just use the product key?
