What is the BIOS setup utility?
The BIOS setup utility is a ROM-based software program. It displays basic computer
information and provides options for setting boot devices, security, hardware mode, and
other user preferences.
How can I start the BIOS setup utility?
To start the BIOS setup utility:
1 Shut down the computer.
2
Press the Novo button and then select BIOS Setup.
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 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 UEFI mode. If you choose to install a legacy
Windows operating system (that is, any operating system prior to Windows 8) on your
computer, you must change the boot mode to Legacy support. A legacy Windows operating
system cannot be installed until you change the boot mode.
