   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).
