BIOS setup utility
What is the BIOS setup utility?
The BIOS setup utility is a ROM-based software. It displays 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
Press the Novo button and then select BIOS Setup.
How can I change the boot mode?
There are two boot modes: UEFI and Legacy Support. 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 need to install a legacy operating
system, such as Windows, Linux or Dos, etc. (that is, any operating system before Windows 8)
on your computer, you must change the boot mode to Legacy Support. The legacy operating
system, such as Windows, Linux or Dos, etc. cannot be installed if you don't change the boot
mode.
