I want the boot menu to display just the Automated install option. I am planning to use the netboot, which I can build from debian-installer checkout by running
make build_netboot (from within
I once needed to alter the boot menu on a debian iso. Note: this was on an older version, and it was not netboot. I hope the points below will be useful, but you may need to adapt them. In particular, check if the path of
isolinux/menu.cfg is correct for your case.
The shell script that I used to do this worked by mounting the iso, making some changes, and then closing it up. After mounting the iso, the script contained the line:
sed -i "s/include live.cfg/#include live.cfg/" isolinux/menu.cfg
This removed live.cfg from the menu, so the install option appeared at the top.
My shell script contained another line you might find useful:
sed -i "s/timeout 0/timeout 1/" isolinux/isolinux.cfg
The idea was to force the menu to timeout after 0.1s
