You have to enter the uefi shell by the same way: Dive into the BIOS and
select it. If the system doesn't boot the boot override function is essential.

I couldn't. The, no, my uefi shell is not self explaining. I failed to start a
running system from the uefi shell. Well, ok, my fault.

So i have to wait until my BIOS company updates it's tools and i can save them
within the BIOS. Back in the old days i had my OS/2 bootmanager and rescue
system on a small partition.

Why DOS? We need to kickstart the boot sequence.
USB stick in addition? I see an EFI partition on my disk in addition.

I've done 50% reading of an efi turorial now and it does remind me to grub.

I'v seen an EFI editor which my bios doesn't have. Now i've to check if anyone
provides this efi software. The default path in my uefi shell does have
something like fs[01234]:/efi/tools. The design concept is to add tools from a
maintenance/rescue partition like we did before from the usb stick or from a
/boot partition.

Maybe the only thing i need is to get used to it...

Regards

Kai
