Hi Vladmimir,

It's quite likely not a problem with the ESP on /boot/efi, but maybe a
problem with the variable storage space on your computer. What make
and model are you using?

I'm also curious about the command line you're using. I'd expect to
see something more like:

  efibootmgr -c -L debian -l \EFI\debian\grubx64.efi

(maybe along with some other options).

grub-install -v will show you exactly what commands grub is trying to
use.
