As above; but at least you dropped a clue, "gdisk".

I initially let d-i/partman automagically partition the SSD, looked at 
the table it generated, and saw a ESP partition, a swap partition, and a 
root partition.  I then wipe the first and last megabyte, created the 
GPT partition with parted, and then proceeded with the complex disk 
layout I really wanted.  Unfortunately, debian-9.1.0-amd64-xfce-CD-1 d-i 
blew up trying to install GRUB, so I don't know where GRUB ends up when 
UEFI firmware and GPT partitioning is done correctly.  That's why I plan 
to try again with the simplest automagic partitioning and see what happens.


STFW I found another useful article:
