In your situation I would install:

grub-efi-ia32

accept that it's going to remove (probably) grub-efi-amd64 and 
grub-efi-am64-bin .

And then install the new grub with just:

sudo grub-install # Grub should autodetect EFI and install there.


If your system has the EFI partition mounted in /boot/efi you should be 
fine.


I'm still interested in your feedback trying Super Grub2 Disk which I 
have discussed with you in a private email.

If you do enough tests who knows if you might finish convincing me on 
building a refactored Ubuntu installation disk which boots from EFI-32 
thanks to Super Grub2 Disk (or Grub2 technically speaking, but it's 
easier for me if I put everything in there).
