So, I just got a new Mac. I need to install Windows on it with Parallels or Boot Camp though for some things (like Army Builder).. anyone have any advice for installing from scratch? I wanna get Windows 7, but it's like $200. Looking at newegg.com, they have a $99 "OEM" version, is that all I need? It says "This software is intended for pre-installation on a new personal computer for resale." .. Well I'm not reselling it, but is it still the same windows? Also, I have a Windows XP CD (the very original one, not SP1 or 2 or whatever), so could I just get the upgrade version if OEM isn't what I want? The XP CD is an upgrade version as well, but my Windows 98 CD that I used for the upgrade is nowhere to be found and most likely long gone. I remember reading that Macs need at least XP SP2, so I'm afraid the XP CD won't be readable or something dumb like that. I want it to be as cheap as possible. Is the $99 OEM the best I can do?
