I think the label is not important, and I have also seen "EFISYS". 
However, EFI is a partition type on GPT partition tables (type `EF00`).

On MBR partition tables, it's type `EF`.

As an alternative to this long section:

I suggest Boot-Repair.

I did this yesterday.

Just `apt install grub-efi` is enough.

Once you install the UEFI version of GRUB, it removes and replaces some 
of the old BIOS version.

Once you have done this, just `grub-install /dev/sda` should be enough. 
Worked for me, yesterday.
