The process of installing a Windows OS is really pretty straight forward-if somewhat lengthy. You put in the disc, follow instructions, and let the process run. One note from experience with XP: once you have the installation process going, if the machine says "hit any key to boot from CD," (or similar prompt) just ignore it. Way too many people goof up a perfectly good install by actually restarting it this way. Once you've gotten started, just answer questions and tell the machine stuff it needs to know, and you'll be fine.
