One of the better sites I have run across is written by a fellow Microsoft MVP: Michael Stevens
Setting
up Windows XP is not that difficult. I'm not going to guide you step-by-step
on how to install Windows XP. There are many sites out there that already
do that, so why waste my time showing you how. Rather I will provide
some links to the best sites (in my opinion) that not only walk you through
the installation process but show you how. Having these links here is a
convenient way for you to access depending on how you plan on installing
Windows XP.
