Hello forumgoers! I have a Late 2011 MBP and am trying to download a trial of Windows 7 by means of Bootcamp. I found a system repair .iso that works for 30 days until you buy an activation key, (which I will order soon). I downloaded it and tried to burn it to disk through Disk Utility. When I select the image and click burn, I get the error, "Unable to burn 'X17-58997.iso' (not recognized)". I looked around but no thread gave helpful answers on any website. If you need any more info I'd be glad to provide it and am looking for a solution before this friday, and one tonight would be greatly appreciated! Thanks all!
