Choosing The System Boot ModeSystem 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 toinstall your operating system from that mode. Thereafter, you must boot the system in the same bootmode (BIOS or UEFI) to access the installed operating system. Trying to boot the operating system fromthe other boot mode will cause the system to halt at startup.NOTE: Operating systems must be UEFI-compatible to be installed from the UEFI boot mode.
