I've looked through the forums and couldn't find an answer to this so here I go. I'm trying to find the cheapest legal copy of XP to install on my imac (as much as I hate to do it) and have found a couple of sites selling legal OEM copies for around $50, the only problem is some of the say "FOR PC ONLY, NOT MAC" such as this one; http://cdsfu.com/index.php?categoryID=87 . Is that something that should worry me? I just don't want to buy something that I can't return and have wasted my money but I really don't want to pay tons of money either. Can anyone suggest maybe the cheapest way to go to just get the most basic form of windows on my mac? Also, I have an acer laptop that is going into the trash but it only has acer disks, is there any way to move that copy of windows legally?
