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.
• 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 overlays the system BIOS.
To select the system
Boot Mode
:
1.
In
System Setup
click
Boot Settings
and select
Boot Mode
.
2.
Select the boot mode you want the system to boot into.
NOTE: After the system boots in the specified boot mode, proceed to install your operating system
from that mode.
CAUTION: Trying to boot the operating system from the 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. DOS
and 32-bit operating systems do not support UEFI and can only be installed from the BIOS boot
mode.
NOTE: For the latest information on supported operating systems, go to
