I wanted to try the manual way to learn + to create my EFI boot entry with a customized name. I think GRUB installation can only create EFI boot entry with the name "debian", or is it possible to change that?

So I must have forgotten to set the other ESP as "do not use", stupid me (I switched from MBR + BIOS to GPT + UEFI setup not so long ago and I guess it shows:). But is there a reason why DI partitioning does not set all (or previously existing) ESPs by default to "do not use" and let the user change that manually (perhaps with a reminder message if the user forgets to set the ESP in UEFI mode)? Maybe it would be more intuitive + it could avoid/minimize user errors? Or is a shared ESP so common that DI partitioning needs its current defaults?

Anyway, thanks for such a quick reply.
