The BIOS can be reset by accessing the BIOS setup during the boot process and reverting its values to its default state. The BIOS setup can be accessed by pressing the right keys during the boot process. The key to enter the BIOS is shown on the screen during the boot process.
- Access the BIOS setup
Turn on the computer. If it's already running, shut it down and restart it. During the boot process, the computer shows a message on the screen that tells the user to press a particular key to access the BIOS setup. Look for this key, and once the key is identified, press it to enter the BIOS setup. If unsuccessful on the first try, restart the computer once again, and try to enter the BIOS setup.
- Reset the BIOS
Once in the BIOS setup screen, look for the option that resets the BIOS to its default values. This option can either be found in the list of options from the BIOS setup screen, or it can be associated with a function key. The actual phrase may vary from one computer to another, so look for phrases like Factory Default, Clear BIOS, Setup Defaults, etc. Once this option is found, select it to reset the BIOS to its default values. When prompted, press Y for yes, or select Yes from the options displayed.
- Save the changes and exit the BIOS
Once the reset process is done and the values have been reverted to their default state, select Save and Exit from the BIOS setup screen to save the changes. This typically restarts the computer.
