Choosing the system boot mode

NOTE: VxRail appliances require the boot mode to be set to BIOS.

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.

• Unied Extensible Firmware Interface (UEFI) (the default) boot mode is an enhanced 64-bit boot interface. If you have congured your

system to boot to UEFI mode, it replaces the system BIOS.

NOTE: The appliance supports only BIOS boot mode.

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

2 Select the UEFI 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 specied 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.

• For the latest information about supported operating systems, go to Dell.com/ossupport.
