As long as all you do is install the Recovery Console that should work.
First make sure you and her have the same, Home or Professional.
You can also install the Recovery Console with these floppies:

Be sure to get the correct download.
Power off
Desktop:...Open the case and reseat the hard drive IDE ribbon cable at both

Otherwise go to the website of the hard drive manufacturer and download
their hard drive diagnostics.
Do you have a hard drive overlay such as Max Blast?
Windows XP sometimes has issues with overlay software.
You may need to perform a Clean Installation without their overlay software
which is not needed anyway.
