How to Format a Computer Through the BIOS

Formatting a computer is the process of deleting all information currently on the hard drive. This is done as an extreme step when changing operating systems or when your computer is infested with a virus. Formatting a computer requires that you set up the process through the BIOS, enabling your computer to avoid loading the operating system, as the computer cannot be fully formatted while the OS is running.
