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.
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 and you then proceed to install your operating system from that
