You may be able to save the data from the hd by installing it as a slave hd in your computer and moving the data, then format it.
Reinstall it in your daughters computer as the master, change the boot order to cd first in the bios, and install XP.
The XP Installation CD and 25 digit Windows Key must be new and never have been activated on any other computer for the required activation after installation to be valid and XP to remain accessible and working. If it has ever been used before on any other computer it will fail activation and then shut itself down and become inaccessible after 30 days.
