DESCRIPTION:

The kboot command boots a legacy OS. If the requested device is not
present, boot returns to shell. The kboot command cannot boot native
uEFI-aware operating systems. But since these are bootable from shell
by calling their bootloader, this is not necessary either. If a requested
device is present but not bootable, uEFI continues to boot with the next
bootable device in the boot order.
