I am trying to use boot camp to partition my mac... and failing.
Every time I try to partition my mac going through the bootcamp steps it keeps telling me that "Your bootable USB drive could not be created, An error occurred while copying the Windows installation files." I found a video that shows how to fix this problem, but only if you are using a CD to download Windows, but I bought it from the windows store online so its an exe file. The instructions say that I need a USB drive (which I have) and a Windows 7 or later version (I have windows 8.1 pro) ISO image downloaded from Microsoft. I bought my windows directly from their store, but I don't understand why the file won't work. I clearly don't have the correct file/ISO image situation so please please please help me out.
Mac Pro, OS X Yosemite (10.10.3)
