Recover Vaio to Original Factory Settings

[Blencogo]

If your Recovery Partition is still on your hard drive, all you have to do is to tap F10 repeatedly during the boot sequence - when you see the first Vaio Logo screen.

This should start the Recovery Wizard - follow the screen instructions to make a Complete Recovery. This may take a few hours, so make sure you are connected to AC Power. Do not interrupt the recovery even if it appears to stop!
