Choosing the system boot mode
System Setup enables you to specify one of the following boot modes for installing your operating system:
•
BIOS boot mode (the default) is the standard BIOS-level boot interface.
•
Unified Extensible Firmware Interface (UEFI) boot mode is an enhanced 64-bit boot interface. If you have configured your system to
boot to UEFI mode, it replaces the system BIOS.

From the
System Setup Main Menu

Select the boot mode you want the system to boot into.
CAUTION:
Switching the boot mode may prevent the system from booting if the operating system is not installed in the
same boot mode.

After the system boots in the specified boot mode, proceed to install your operating system from that mode.
NOTE:
Operating systems must be UEFI-compatible to be installed from the UEFI boot mode. DOS and 32-bit operating systems
do not support UEFI and can only be installed from the BIOS boot mode.
