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.
-
NOTE: Dell Storage NAS supports only
BIOS mode. You must not change the boot mode to UEFI because the system
does not boot.
- 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, click
Boot Settings, and select
Boot Mode.
- 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.
