I got the 40 dollars windows 8 and the 15 dollar backup dvd. Now how to install it on my mac mini i5 2.3 8gb ram. I don't want to partition or format 10.7. The parallels I have is from 2007. Like 1.0 I think. So that won't work. Is there anything else I can use to install windows 8 (even if I have to buy it). Or will it install to an external hard drive.
