I talked about cases where something is broken and your system doesn't boot
(maybe not even the bootmanager comes up). With MBR this means reconfiguring
BIOS boot order, probably getting some USB media to boot a rescue system from
it etc.
With the built-in UEFI shell, you can already check your partitions and even
select what to boot without having to reconfigure anything or to provide a
rescue system on USB. In many cases I was able to manually boot the failed
system with this and use the system itself then to fix booting.

Some manufacturers provide firmware and bios update tools on efi meanwhile. In
that case, you can just drop the new firmware and the upgrade tool on a USB
stick and use UEFI-shell to run it from there. In the MBR-days you would have
needed to have a MSDOS-system on the USB stick in addition (and hope that the
manufacturer would still provide a DOS-based update tool that is able to run
on your newly bought server or workstation).


Regards,
Gerrit
