From what little digging I did we have have access to a windows computer and a full version of windows.
You then download the windows ISO image on a jump drive, that's formated to (FAT, iirc)....that's were access to a windows computer comes in.
Once all that's done, then ya take your windows loaded jump drive....plug it into your MAC and go through the boot install assistance.....I used the search bar in the launch pad on my MAC to find the boot assistance.
I haven't tried to complete everything but that's what I've researched so far.
