I would like to have a fully automated debian install iso. For that I started by creating a custom iso with a preseed integrated in the /isolinux/txt.cfg but I would like to bypass the menu of the grub to proceed directly to the installation (not having to manually select "Install" on the menu .
When I manually select Insall, the preseed file is well used.
I am still in the testing phase, I use the example on the debian site as a preseed file: https: //www.debian.org/releases/buster/example-preseed.txt
Here is my txt.cfg file:
label install
menu label ^Install
kernel /install.amd/vmlinuz
append vga=788 initrd=/install.amd/initrd.gz file=/cdrom/preseed.cfg --- quiet
Thank you in advance for your reply
