I use Ubuntu 18.04 on my computer. This Ubuntu installation appears as ubuntu at system EFI boot menus.
I also have a external USB storage that has a EFI Ubuntu installation. This external USB storage also appears with the name ubuntu at system EFI.
I see two ubuntu menus at system EFI boot menus when external USB storage is attached. This makes it hard to figure out which ubuntu menu item points to the Ubuntu installation on the computer, and which one points to the Ubuntu installation on the external USB storage.
How I can change the EFI boot label to something different?
For example, how can I change ubuntu EFI boot label on the external USB storage to appear as External Ubuntu at system EFI boot menus?
The Ubuntu on my external USB storage has its own EFI partition.
This question is different from How to safely change OS name in grub boot menu?
This question is about how to change the Efi Boot name that appears in the EFI Firmware setup and not in the GRUB boot menu.
