I had to reinstall windows xp on my computer.
I had to reinstall windows XP but not from the original CD. i never recieved the original when i bought my computer.
So I used Dell XP reinstall CD and typed the product key that I have for that machine.
But it won't work for activation. what do i have to do
The Dell reinstllation CD is only going to work properly on a Dell computer. The installation of XP that it puts down is looking for data on the motherboard that only a Dell motherborad can provide, which is why it won't activate.
Please contact your computer manufacturer's tech support or customer service people to find out how to acquire the specific reinstallation or recovery discs your computer needs.
