Dual booting windows 7 and windows 8 to me is hardly a dual boot... let's be serious you can do anything you want with 7 as u can do with 8 and vice verca. I am talking about linux/windows dual boot so you can do things you can't do with both of them. As for installing OSX on a PC I have done it many times... is it legal? Ask apple hahaha ... Why not add XP and vista to your boot, while you're at it, Windows 95!
