[jaffa156]

Im kinda new to this and not really sure about sorftware, but i have a toshiba laptop with vista installed on it, but its really poor and i much much prefer XP. My parents have a dell PC and have a reinstallation disk for XP with it, would it would if i used this on my laptop? and would i need to activate it somehow?

Dell discs work only with Dell computers.
