How to enter the BIOS to change your PC or laptop’s settings

Your PC’s BIOS (Basic Input Output System) is responsible for controlling the basic functions of the computer. It holds the time and date, along with configuration settings such as the boot order and the speeds at which the processor and memory run. It also determines whether certain components are enabled or disabled, such as USB ports and the on-board audio processor.

A common reason to enter the BIOS is to change the boot order. Perhaps you’ve installed a new hard drive, or need to boot from a CD or USB flash drive. You’ll need to alter the list which determines in what order devices are tried to see if they contain bootable software.

How to enter the BIOS

1. Press your PC’s power button and wait until you see an image appear on the monitor. Press the appropriate key repeatedly. Common keys are Delete and F1, but some systems use F2, F5 or F12. Bear in mind that some wireless keyboards may not work before Windows loads, so use a wired keyboard if possible.
