I am a mac user but woud like to install windows 8 or 8.1 wtever on my mac. I would like to do bootcamp for this. I found a stduent version of windows 8 and purchased that but it turns out it's an exe file and I couldnt open it on my mac. It seems that I need an iso file but whats that actually? Where can I purchase an iso file of windows 8 legally on internet? I dont have any windows store in my town. Also I got a problem when I tried bootcamp it said I need a CD or DVD but i dont have one. Can't I just do it by my USB? Please can sb help me with this I need a windows so badly. Thanks a lot!
