Hi Steve,
I followed your instructions and copied /boot/efi/EFI/Ubuntu 16.04.2
LTS/mach_kernel to
/boot/efi/EFI/ubuntu/mach_kernel
I then installed grub manually using a modified command from same
guide I referred to earlier
sudo grub-install --target x86_64-efi --boot-directory=/boot
--efi-directory=/boot/efi --bootloader-id="ubuntu"
The install succeeded!
Please find below the terminal printout and attached trace files.
I will attempt to restart the system after I send this message. Thanks
for your help! :)
