One possible complication that I overlooked is that you mentioned Dell.
If this is a Dell computer then you will be limited to Dell Recovery Options.
The Stevens' page was intended for use with Microsoft's XP CD.
Dell has an interactive Recovery guide here:

(insert your model)
How Do I Install the Microsoft® Windows® XP operating system on My Dell Computer?
Unfortunately at a quick read it also requires backing up data to removable media. Here you could consider thumb drives and or any type of external drive.
Again removing all burning software might give your current system a chance to burn.
As to SP2 I download it and burn to disk so one does not have to go on-line. Perhaps you can do this on another computer or again a repair install should leave it on your current drive assuming that you can perform a Repair Install on a Dell.
Anyway the download is here:
