That is not what im saying. My mistake if i didnt use correct terminology or i misleaded you. What happends is, i get to the xp prompt to where it says, enter your product key, then i enter the key, then it says its invalid when i press next. I cannot get beyond that point to where i am able to install windows. I hope that clears everything up. Like i said my serial is legitimate. It is not working only on this stuburn laptop.
