Formatting toshiba laptop

First restart your Toshiba laptop. Press either "F1," "0," or "F8" to be taken to your computer's hard drive utility screen. The key command differs depending on the model Toshiba computer that you own.

Select "Restore Original Factory Image" from the list of options in System Recovery. Verify that you want to continue the process by clicking "Yes," then click "Next".

Restart the Toshiba laptop once the factory restore process has been completed. You will be prompted to enter information such as the date, time and language preferences.

Some manufacturers provide a recovery partition that you can boot from. You can try pressing F8, F11 or F12 repeatedly on startup to attempt to access this. If not, you will need to use your recovery DVDs. If you do not have these, you will either need to create them if you can still access your laptop's operating system, or you can order them from Toshiba.
