GRUB non-EFI Boot Menu

Use this option to add an additional menu item in the boot menu for the ISO, which will allow an automated install after setting preferences and potentially using any utilities on the standard boot menu.

This is for legacy (non-EFI/BIOS) systems.

Alternative Configurations:

0644 root root custom-iso/isolinux/txt.cfg
 6default custom-saltstack
 7label custom-saltstack
 8  menu label ^Install Ubuntu Server w/ Saltstack minion
 9  kernel /install/vmlinuz
10  append file=/cdrom/preseed/ubuntu-saltstack.seed vga=768 debian-installer/language=en debian-installer/country=US console-setup/ask_detect=false keyboard-configuration/layoutcode=us debian-installer/locale=en_US.UTF-8 localechooser/preferred-locale=en_US.UTF8 initrd=/install/initrd.gz quiet ---

Note

This assumes you place the custom entry first. Adjust default accordingly.
