A Toshiba laptop can be restored to factory settings using the built-in Toshiba HDD Recovery Utility. This utility comes installed on all Toshiba laptops and does not require you to install any additional software to be able to use it. Restoring the laptop will delete all the files, including system configuration files, and your laptop will be restored to a state similar to what it was when you first purchased it. Restoring to factory settings only reconfigures the software part of the laptop and does not in any way affect the hardware.
Restart your Toshiba laptop and then press and hold the “0” key on the keyboard until you see the Toshiba HDD Recovery Utility dialog box.
Press “1” on your keyboard to select the “Restore Original Factory Image” option.
Click “Yes” on the dialog box that opens to confirm that you want to restore your laptop to the original factory settings.
