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.

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.
1. You must select the boot mode in the Boot Mode field of the Boot Settings screen of System Setup.
2. Once you specify the boot mode, the system boots in the specified boot mode, proceed to install
your operating system from that mode.
3. 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.
