I have inspected the following webpage: https://www.kernel.org/doc/Documentation/admin-guide/kernel-parameters.txt And I cannot find out the parameters/arguments used here: `findiso' and `components'. > initrd (loop)/install.amd/gtk/initrd.gz > } > menuentry --hotkey=i 'Install' { > set background_color=black > linux (loop)/install.amd/vmlinuz vga=788 findiso=$iso_path > components --- quiet > initrd /install.amd/initrd.gz > } > > > > or even, > 2.)

The first grub.cfg used by the iso is: /EFI/debian/grub.cfg This file will then source all of the other grub.cfg, including the one in /boot/grub/grub.cfg, which is the last grub.cfg in the chain. > } > > > But the latter is unlikely to work because again, that config is > expecting to be running grub itself so the paths are probably not going > to be correct. > > > I recommend instead using a generic name for the ISOs (e.g. > "debian.iso") so you don't need to edit/regenerate the grub.cfg for the > USB device every time you update the ISO. > > > -- > brent saner > https://square-r00t.net/ > GPG info: https://square-r00t.net/gpg-info > -- Hongsheng Zhao <hongyi.zhao@xxxxxxxxx> Institute of Semiconductors, Chinese Academy of Sciences GnuPG DSA: 0xD108493
