The CD you received from Dell with the laptop. If you lost that contact their customer service.
I have a inspiron 5150 with Windows XP Home product key sticker on the back of the laptop. What XP install cd so I need to activate it? The HDD is wiped clean.
I have a burned cd that someone sent me an .iso image to burn for my other laptop but the harddrive already had xp installed in it. And it just booted right up without me having to type in a key. But when I try it on the other one it activate's a trail version and the product key on the sticker won't activate.....
Thanks in advance..
