Hi,
has it already been tested whether a grub-mkrescue ISO boots to a GRUB prompt ?
To try it, install
grub-common grub-pc-bin grub-efi-amd64-bin
run
mkdir minimal touch minimal/empty-file.txt grub-mkrescue -o output.iso minimal
and use output.iso like groovy-desktop-amd64.iso.
No menu or so is to be expected. Only "grub> _". https://i.stack.imgur.com/DEL0D.jpg
-------------------------------------------------------------------------
I really doubt that it makes a difference, but if a grub-mkrescue ISO boots, we could try its pure GPT partition table by xorriso -as mkisofs option
-appended_part_as_gpt
which produces a "Protective MBR" partition table which indicates a valid GPT.
If GPT does not boot either, then the difference must be in the EFI partition. Either its storage location or its content.
The location could be tested by a stripped-down groovy-desktop-amd64.iso with fewer payload but full boot equipment.
About the content of the EFI partition i cannot say much.
Have a nice day :)
