Dual booting with Windows XP

Been browsing Microsoft's website a lot here lately, looking for some good information that I can pass on too you all. Found a series of how to articles, one of interest in particular, dual booting, or multibooting as they call it, with Windows XP, a subject I haven't covered much yet. From their site, "You can install two or more operating systems on your computer, and then choose the one that you want to use each time you restart. This is known as multibooting. You can configure your computer to start Windows XP, Windows 2000, Windows NT, and either Windows 95 or Windows 98 or Windows ME." Here is the link to the main page, here is the article for installing Windows 2000 and Windows XP, this article is for Windows NT Workstation 4.0 and Windows XP, and this article is for dual booting MS-DOS, Windows 95, Windows 98, Windows ME and Windows XP, be aware that each of these links are for different pages of the same article, so if you just want to read the whole thing and not a particular setup, then start here. In almost all cases, Windows XP must be installed last, and in the case of pc's that participate in Windows domains, each installation must use a different computer name, because a unique security identifier (SID) is used for each installation of Windows XP on a domain, the computer name for each installation must be unique—even for multiple installations on the same computer.
