BIOS setup utility

What is the BIOS setup utility?

The BIOS setup utility is ROM-based software. It communicates basic computer

information and provides options for setting boot devices, security, hardware

mode, and other preferences.

How can I start the BIOS setup utility?

To start the BIOS setup utility:

1. Shut down the computer.

2. Repeatedly press and release the F1 key once turning on the computer to start

the Setup Utility program.

How can I change the boot mode?

There are two boot modes: UEFI and Legacy. To change the boot mode, start the

BIOS setup utility and select Startup

→

Boot Priority, then set boot mode to UEFI

or Legacy support on the boot menu.

When do I need to change the boot mode?

The default boot mode for your computer is the UEFI mode. If you need to install

a legacy Windows operating system (any operating system before Windows 8) on

your computer, you must change the boot mode to Legacy support. The legacy

Windows operating system cannot be installed if you don’t change the boot mode.
