Providing you have XP pro on the laptop as well, then yes.

And providing that the Desktop is a Dell.

In the future, by using the Advanced Forum Search on the bottom of this page, you can quite easily find the answer to this often asked question.

 

Provided you have an unused Pro key, and you download all drivers beginning with chipset and notebook system software, and you reinstall all software, you can install Pro on it.

what do you mean i have to have a dell desktop in order for me to use my windows xp cd.

 

He means that since you said your desktop came with Pro, and you want to use that CD for your notebook, that you can IF the notebook came with Pro.  If the notebook came with Home, then you cannot do this, it's illegal, violates the license agreement, and also violates the terms of service of this forum to discuss it.

You're getting confused by posting in the middle of someone else's thread...

 

I already answer your question pretty clearly - you can use a RETAIL copy of XP PRO if you have a unused key, and then install all your drivers starting with chipset and notebook system software.
