If the recovery area data has been corrupted or erased, you can use Recovery Media to recover your VAIO computer.
However, recovering the computer using the Recovery Media will take longer than using the recovery area.
If you use Recovery Media (optical discs) on the model without a built-in optical disc drive, connect an external optical disc drive (not supplied) to the computer. See Connecting an External Drive for more information on how to connect the external optical disc drive.
If an AC adapter or a power cable is supplied, plug it into a power source.
Follow the on-screen instructions until the Choose an option screen appears.
Follow the on-screen instructions until the VAIO Care (Rescue Mode): VAIO recovery solutions screen appears.
If the display language selection window appears, select your desired language, then OK.
To perform custom recovery, select Tools and Start advanced recovery wizard.
If you cannot recover your VAIO computer using the USB flash drive, connect the drive to another USB port on the computer, and then try recovering the computer again.
