You are right. It works without using the APPEND option,like this : (inside the file grub.cfg)
menuentry "Custom Graphical Debian Installer" { linux /d-i/gtk/vmlinuz file=/cdrom/preseed/preseed.cfg auto=true video=vesa:ywrap,mtrr vga=788 "${loopback}" initrd /d-i/gtk/initrd.gz } anyway,I don't know if it's correct to use something like this in the ISOLINUX/menu.cfg file : LABEL Custom Graphical Debian Installer SAY "Booting Custom Graphical Debian Installer..." linux /d-i/gtk/vmlinuz APPEND boot=casper file=/cdrom/preseed/preseed.cfg auto=true initrd=/d-i/gtk/initrd.gz append video=vesa:ywrap,mtrr vga=788 the APPEND parameter that you see was there by default. Is that correct ? Otherwise,is something like this ok ? linux /d-i/gtk/vmlinuz boot=casper file=/cdrom/preseed/preseed.cfg auto=true initrd=/d-i/gtk/initrd.gz append video=vesa:ywrap,mtrr vga=788 Il giorno gio 13 ott 2022 alle ore 18:00 Thomas Schmitt <scdbac...@gmx.net> ha scritto: > Hi, > > Mario Marietto wrote: > > ... > menuentry "Debian Custom Graphical Debian Installer" { > > ... > linux /d-i/gtk/vmlinuz APPEND file=/cdrom/preseed/preseed.cfg > auto=true video=vesa:ywrap,mtrr vga=788 "${loopback}" > > ... > initrd /d-i/gtk/initrd.gz > > > If I remove the argument APPEND,the only other chance that I have to pass > > the preseed file is to add it inside the initrd file. > > To my understanding this passing is achieved by argument > file=/cdrom/preseed/preseed.cfg > with no need for a preceeding argument "APPEND". > > > > If you will read on the preseed tab on cubic > > For that i'd need to know where this tab is. > > > > they suggest to prefix the preseed > > file with the word "cdrom" in the boot configuration. > > If it works for you then it's a good hint for others. > > > > And I don't understand why you are talking about ISOLINUX, > > Because "APPEND" in a separate line is a SYSLINUX/ISOLINUX configuration > directive and because you wrote on Tue, 11 Oct 2022 23:17:39 +0200: > > > ... > I'm trying to modify them as follows : > > ... > isolinux/menu.cfg > > ... > LABEL English (en) > > ... > SAY "Booting English (en)..." > > ... > linux /live/vmlinuz boot=casper APPEND > file=/cdrom/preseed/preseed.cfg > > This is the configuration file for ISOLINUX which boots on legacy BIOS. > > (I think it is wrong by not giving APPEND an own line, so that ISOLINUX > would recognize it as configuration directive.
