Are you using the appropriate kernel cmdline args in the menu entry? They're different from Arch's grub loopback menu entry.
This is just what I stucked on. I failed to figure out the correct cmdline args used for linux and initrd.
Useless. This is for Debian *live* instead of Debian *install* iso, the image I use for install Debian is:
http://mirrors.ustc.edu.cn/debian-cd/10.1.0/amd64/iso-dvd/debian-10.1.0-amd6...
The live CD contains the installer. They're functionally the same, more or less, and are created by the same tool/use the same init.
The only difference from that article is:
bootoptions="findiso=$iso_path boot=live components quiet splash"
would instead match the boot entry of the installer ISO. e.g. these are directly from the install ISO's grub menu ([iso]/boot/grub/grub.cfg):
menuentry --hotkey=g 'Graphical install' { set background_color=black linux /install.amd/vmlinuz vga=788 --- quiet initrd /install.amd/gtk/initrd.gz } menuentry --hotkey=i 'Install' { set background_color=black linux /install.amd/vmlinuz vga=788 --- quiet initrd /install.amd/initrd.gz } (...)
SO you can either:
1.) Use the following:
set iso_path=path/to/debian-10.1.0-amd64-DVD-1.iso loopback loop "$iso_path"
menuentry --hotkey=g 'Graphical install' { set background_color=black linux (loop)/install.amd/vmlinux vga=788 findiso=$iso_path components --- quiet
I tried with this settings, but still failed with the following error: No Common CD-ROM drive was detected. So, it seems these options are only for live images -- ie, which uses squshfs to store the os image.
initrd (loop)/install.amd/gtk/initrd.gz } menuentry --hotkey=i 'Install' { set background_color=black linux (loop)/install.amd/vmlinuz vga=788 findiso=$iso_path components --- quiet initrd /install.amd/initrd.gz }
or even, 2.) Use the ISO's grub file directly:
set iso_path=path/to/debian-10.1.0-amd64-DVD-1.iso loopback loop "$iso_path"
menuentry 'Debian' { configfile (loop)/boot/grub/grub.cfg }
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.
