I am confused myself. But from the responses, it looks like (hd0,gpt1) is 
the correct form. Not (0,gpt1). grub manual is at 
https://www.gnu.org/software/grub/manual/grub/grub.html . I would try to
    ls (hd0,gpt1), or ls (hd0,gpt1)/, and so on, in order to see if I am 
acting reasonably.

Are you able to boot the installation media from usb, and start a rescue 
session? The emphasis here is to start a rescure session. It is probably 
a command line environment.

With those partitions, where is /boot located?

 system your efi partition has? And your boot

Assuming you are comfortable enough with the installation rescue session:
From within the rescue shell, what are the toplevel directoriesunder the 
boot/ directory?
In general, my suggestion is to keep a record of the commands you issue, 
and their responses. I think the rescue shell does not have a script like 
command. So one should write it to paper, or take photos with his cellular 
phone, or something. Actually, you seem to already done that for the grub 
session. So just be systematic about those records.
