Bootable Media Creator (BoMC) supports creating Extensible Firmware Interface (EFI) bootable media. Unified Extensible Firmware Interface (uEFI) supports two types of boot modes: Legacy and EFI. This requires that the boot modes in the uEFI setting are set to UEFI Only or UEFI and Legacy. Beginning with version 9.50, BoMC no longer supports the legacy only boot mode.
