Installing 2 windows

I'm trying to install 2 versions of windows. I have windows xp home edition bundled with software but only on a recovery partition. I want to install a version of Windows with IIS. I have copies of Windows 2000 (which i dont really want), and preferably windows Server 2003, or xp pro. How can i install both of these on my computer so that when i want to be able to switch between the windows so that i can do everyday computing and IIS work. when i do a recovery to put the original XP home on, and then another OS, it give me a loader but when i try to load xp home it says it's missing some file ( if u need the exact message let me know). any suggestions.

simply run the install, when it says a previous version found, choose a different directory for the new install....i.e. xppro, win2003...etc, etc.......this of course is off the top of my head. Just so you know, you won't be able to tab back and forth, you will have to reboot each time you want a different operating system. btw, do not choose the partition that the xphome install data is located..... choose the larger of the volumes it gives you. The recovery volume will generally be around 500MB-3GB
