You cannot copy you must make an ISO of the orignal you are missing files.
B:
I have been lead to think you are using a Dell OEM Xp disc which as you said only works on a dell correct?
Solution:
Make an ISO of the orignal if it is a non vender copy of the cd if it is a OEM/Vender variation then you will have to go out and buy XP to work with your non dell computer.
