Looking for a good tutorial for Dual Booting XP Home and Vista 5472

[leglez]

I recently got Vista 5472 (is this the newest one?), and I want to try it out. Currently I have Windows XP Home SP2 installed on my master 80GB HDD. I have a 300GB slave in, but it also has media and documents. I am wanting to installed Vista on the 300GB but only use like 40GBs (what is required/recommended) of the 300GB HDD. Are there any good tutorials that explain how to do all of this out there?
