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.
1.
From the
System Setup Main Menu
, click
Boot Settings
, and select
Boot Mode
.
2.
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.
3.
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.
