Select the BIOS Boot Mode

The BIOS firmware supports both legacy BIOS boot mode and Unified Extensible Firmware Interface (UEFI) boot mode; the default setting is Legacy boot mode. ESXi supports both legacy BIOS boot mode and UEFI BIOS boot mode, and you have the option of setting BIOS to either legacy boot mode or UEFI boot mode before you perform the OS installation.
