Did she delete the VAIO Control Panel that might give you the option to burn the recovery discs off the hidden partition on the hard drive?
I just loaded XP Pro on a fresh hd in my Vaio and it was a real PIA because you have to have all the proprietary sony drivers instead of the regular XP drivers and it adds an extra hour on a reinstall and even then I couldn't get some stuff to work. They certainly want to drive you through their install discs to insure the sony bloatware is in your face.
