Hi guys. Sorry to bother you with what will most likely turn out to be a simple question. Right now, I have Windows XP Home edition my laptop (how it came when ordered). For one of my classes this semester, I will need to have XP professional on there. I was able to order XP professional from my college for a very good price. It is not the upgrade version of XP pro. It is the full version. The upgrade version was not availbable to be purchased from the college. Is there any installation option (or method of installation) available that won't wipe out my file system? I'd like to not have to reinstall the program I already have on there. Thanks guys.
