Hi thanks for the info!

I'm now test my project bassed on jessie, with the live-build version
from debian git to get a iso image with efi support

I have a live system (installable via debian-installer-launcher) and use
a preseed to complete disable the network support during install (and
another pressed options).

My question is about grub installs fail.. i can not put grub-pc and
grub-efi in same binary image (via config/packages-list/*.list.binary
due a conflict between boot packages. The grub install stage fail.

With networking suport is not problem because the necesary packages are
downloaded. But whitout networking how to solved it?
Thanks!
