How can I re-install windows vista again?

I want to put a new partition, that's why

so, how do i do it?

do I have to 'reset' it?
if yea, then how do I reset it?

dude, when you said that I thought you were just saying crap

ok, i'll look at that. but I'm not gonna pay for anything

pop that Vista disc in the cd tray and reboot..keep tapping the F2 key untill the black and white screen appears,now select install windows....windows will ask you if you want to keep the old partision and i see by your added details you dont so select no. You will be formating a new partision
then let Vista do it's thing and leave everything pluged in printer,speakers etc because Vista will install and update them for you.
Good luck

Ok hmm I though it did work with vista. I am sorry.
You will have to re format your harddrive then. You will need to use your vista disk. Put it inside dvd tray and restart your computer. Tap F2 on the keyboard until you can select install windows. You will have to format the old partition :( to create a new partition.

Think about it, it might not be good to lose all your stuff for this.

Again sorry, I though partision magic would save you some trouble.
