The Toshiba NB205, NB255 and NB305 series netbooks are small and easy to take with you almost everywhere you go. If you start experiencing instability with the operating system, recovering your netbook's factory settings resolves system errors and restores missing system files. But because this process also erases the hard drive, use it as a last-ditch option.
Recover Using Recovery Partition
Plug in your Toshiba NB205, NB255 or NB305 series netbook to a wall outlet using its AC adapter. Shut down the netbook, then hold down the "0" (zero) key and press the Power button to restart it. Continue holding down the "0" key.
