DESCRIPTION:

The kboot command boots a legacy OS. Boot device can be selected in
a very flexible way. 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.
