Changing the boot order

In the System Setup Main Menu, click System BIOS → Boot Settings.

2. Click Boot Option Settings → Boot Sequence.
3. Use the arrow keys to select a boot device, and use the <+> and <-> keys to move the device down

or up in the order.

4. Click Exit, click Yes to save the settings on exit.

Choosing the system boot mode

System Setup enables you to specify the boot mode for installing your operating system:

• BIOS boot mode (the default) is the standard BIOS-level boot interface.
• UEFI boot mode is an enhanced 64-bit boot interface based on Unified Extensible Firmware Interface

(UEFI) specifications that overlays the system BIOS.

To choose the system boot mode follow the steps below.

You must select the boot mode in the Boot Mode field of the Boot Settings screen of System Setup.

Once you specify the boot mode, the system boots in the specified boot mode, proceed to install

your operating system from that mode.

You must boot the system in the same boot mode (BIOS or UEFI) to access the installed operating

system.

CAUTION: Trying to boot the operating system from the other boot mode will cause the system
to halt at startup.
