compatibility with non-UEFI operating systems. This option is set to BIOS by default.

disables the UEFI Boot Settings menu.

Choosing the appliance 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.
• Unified Extensible Firmware Interface (UEFI) (the default) boot mode is an enhanced 64-bit boot interface. If you have configured
your appliance 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 appliance to boot into.
CAUTION
: Switching the boot mode may prevent the appliance from booting if the operating system is not installed in
the same boot mode.
3 After the appliance boots in the specified boot mode, proceed to install your operating system from that mode.
