How to access the system BIOS on a PC

The BIOS is system software embedded inside your computer that helps the computer to start up and to set most of its hardware peripherals.

The initial function of the BIOS is to identify, test, and initialize system devices such as the Video Display Card, Hard Drives, Solid State Drives, USB devices and other hardware.

Every PC and BIOS manufacturer can use a different key or combination of keys in order to enter the System BIOS. Sometimes during system boot when the screen is blank you will see some text in the bottom middle or bottom right of the screen that will tell you what the key sequence is. If not, you may need to consult your computer manual, or contact the manufacturer of your computer to find out what the key or key combination is.

Some of the most common single key commands are:
  • F1, F2, ESC and DEL.
Some of the most common key combinations are:
  • CTRL+ALT+ESC, CTRL+ALT+DEL, or CTRL+ALT+INS.

The BIOS will either display the drive model number or just the capacity.

Reasons for not detecting a drive in the BIOS:
  • The SATA port is NOT enabled - The port may need to be enable by turning it ON in System Setup
  • SATA Connection or faulty SATA cable
  • Faulty drive
