I bought a an E520 over a year ago that shipped with vista premium however some of my software and hardware would not work with vista (no drivers) so installed XP on the c drive keeping the D recovery partition so i could reinstall vista at a later date.When i go into the recovery partition and click the pcrestore.exe i just get an error message(just a red circle with an x).Ive tried f11,F12,F2 and F8 but theres only the option to fix xp.I have no disks so how can i restore the pc to factory condition ?
