I tried installing Fedora as second OS on my new Vaio notebook; but after installation when I tried to boot windows7 it didn't load. Afterward when I tried to recover windows 7 with the built in recoevry partition it initially went well but at the end when it restarted it could not load windows 7 OS. I think my recovery partition has been corrupted. Although now I have retored my system using recovery discs I had created some time back; I want to know can I write my recovery partition from these recovery discs so that next time if I need to recover my system I dont need these recovery discs. More oevr is it possible to restore my recovery partition to its factory settings.

Suggest you consult Sony's web site to see if they provide a way to restore the hidden recovery partition: Sony eSupportMowGreen Windows Expert IT Pro - Consumer Security
