windows xp pro reinstall problem

[Chingis]

howdy all , well got my new beast all up and running , and figured what teh heck lets see if i can get the old machine running just to surf the web and whatnot
here is my problem

i formated the 30 gig drive on my old HP 1.2 althon , using a dell reinstall CD
everythign seemed to go fine, until i need to register my product key , it say the key is invalid , but how can this be its the same key i had on the cpu from b4 , ony thing i did different is use the Dell reinstall CD

now im starting to wonder if Dell has something imbedded on the CD so that it has to use a Dell Product key if there is such a thing ?

i broke my original xp pro cd i had , and picked up the dell replacement for 5 bucks

is there anything i should try or can do?

please LMK

thanks

you need the key on a dell system
your better off getting a copy from a friend
