    Hey guys, i've tried reading up a bit and even watching some videos on this before I go ahead and try for myself. But I really just like to be 100% sure and get definite answers.


    I recently purchased a 27" late 2015 iMac. I want to be able to dual boot for some light gaming purposes and because my CAD program is for windows.

    So from what i understand is that because I possess a windows 7 install key, I am able to download a free Windows 10 iso and use my key with that to dual boot? Charge free?
    I really just want to use Steam on windows, I can deal with not having CAD on this iMac.
    I am sure this question is super redundant, I just always second guess my findings and would like to be re-assured!

    From my own experience as a CAD developer and user on both Windows and Mac, I recommend you to stay with Mac OS and leave Windows for non-Apple devices. Why?

    1. You can find a good and cheap (maybe even free) native 64-bit CAD for Mac OS X (I also developed one, but I don't want to advertise myself here)
    2. If you use macbook then you can work 3-4 times longer on Mac OS (I have a MacBook Air and running 12 hours on OS X compared to 3 hours (even less) on Windows.
    3. You don't have to bother with bootcamp and switching all the time from one OS to another (big waste of time)

    I have done that. Download the Windows 10 iso and install with BCA, but you need the exact same version as your windows 7. Then you can use your windows 7 key to activate windows 10.
    I had a problem where I could not activate when I downloaded the "N version" of windows10.
    I even have Parallels Desktop 11 where I can access the bootcamp partition from OSX. Just needed a second windows 10 key to do that. :(
