Sorry, but that's not the point of the "menu default" entry there. The
full stanza is:

default install
label install
        menu label ^Install
        menu default
        kernel /install.amd/vmlinuz
        append vga=788 initrd=/install.amd/initrd.gz --- quiet 

The "menu default" directive is a command to isolinux to say "this is
the default entry in this menu". There's already a "menu label
^Install" directive there. See


for docs on isolinux menus. Grub's support for isolinux menus is
clearly not complete/correct here, and that's your problem I'm
afraid. Isolinux parses these menus just fine.

In fact, I've seen this exact problem myself on a Libreboot machine
when trying to install Jessie a few weeks back. What I did in the end
was drop to a grub command prompt and start the installer by hand that
way. It looks like a (design?) bug that Libreboot won't do normal boot
sector booting like a conventional BIOS.
