Your Sony Vaio computer loads a program called the BIOS (Basic Input/Output System) every time it is powered on. The BIOS determines if any of the hardware components are not working properly and also decides how the operating system is booted. If you need to change settings such as the system time or want to enable your Sony Vaio to boot an operating system from a USB drive, you can do so by entering the BIOS menu.
Close any open programs. Restart the Sony Vaio computer. Repeatedly tap the "F2" key as the Vaio restarts until the BIOS menu appears.
Use the arrow keys to navigate through the BIOS menu. Tap the "Enter" key to choose a submenu or to select an option you want to change.
Press "Escape" to exit a submenu and return to the main BIOS menu. Use the arrow key to highlight the "Save & Exit Setup" option when you are done making changes. Press "Enter" to save your changes to load the operating system.
Highlight "Exit Without Saving" and press "Enter" instead if you don't want to save the changes you made.
You can also press the "F10" key to save your changes and exit the BIOS menu at any time.
Save any important documents you have to an external storage device before entering the BIOS. If you change the wrong setting, you could potentially prevent your Sony Vaio computer from loading its operating system correctly.
