Dell W2K CD - Convert to Normal W2K CD?

I have a dell laptop (Latitude C610 P3 Tualatin 1000 - wootz) that came with windows 2000 pro "2 cpu" licence, and i dont use windows 2000 for the laptop - i use xp, and im wondering, can i convert/modify and remake a new windows 2000 cd to use that licence on another machine? When i use the disc in any other machine it tells me its a dell only cd, is there something i can modify to get it workin as a normal cd?

Would it be legit if i downloaded a copy of windows 2000 and used my legit copy cause its going to waste...
