I'm trying to reinstall XP on my sister's old Dell machine. It has a product key on the side so i (foolishly*) used my XP Pro OEM CD to format and start the install. *Foolish, because the product key was for XP Home. Hence i got as far as putting the key in, then it didnt like it. So i found out that i need an XP Home OEM disc to work with that key. I couldnt find one through friend's etc. but eventually one of my mother's friends gave us an XP Pro OEM CD with it's own key. I thought i was onto a winner with that, but it doesnt like the key that came with that CD either. I continued the install with my CD and then tried to enter the new key.
Now, my stupid question is -- does it not like the key because i started the install with *my* disc, and i'm entering a key for another disc? I'm sure it doesnt work that way, but it's worth asking! If so, how do i get back to the beginning of the install, as everytime i boot it just asks for the CD to continue the install.
My second stupid question is; what happens if i just use my key?
Short of that, would Dell send me a new disc for free? If so, would information do they normally need? It was my sisters PC so she's lost anything and everything to do with it - i've literally just got the box itself!
Thanks for any advice
