Well not really sure how i was going to do it, are there any guides on the net i did a quick search but couldn't find anything specific.
Basically i just wanna do it as easily as possible without really losing any work, i mean i could just back everything up to my laptop or onto DVD, which might make things simpler, but id rather just keep it on the PC, and use a dual boot for both XP and Vista.. (If that's possible...

)
Edit: Also wanted to do it for free or at least the cheapest and easiest way? (Sorry for all the questions!)
Also has the download link worked for anyone yet?
