Set a password for grub, and it seems did missed some hash digit when copied encrypted password in 40_custom,
I managed to removed login/password details from grub /etc/grub.d/40_custom using rescue disk.
but now update-grub needs to be run, sins grub is not loading, and neater the kernel, obviously setting a cron job to run it is useless,...
Does anyone knows if there is a solution to add a command to grub, to run update-grub at load time in GRUB_CMDLINE_DEFAULT="command_to_run_update-grub" ?
Or may be there is a way to do manually what ever update-grub does ?

Since you have access to the root filesystem using some external applications, why don't you just reinstall grub? That way you can boot to your system once again.
Here's a tutorial on how to reinstall grub on a Debian distro. Based off of this tutorial, you could also try running the update on the rescue mode without reinstalling.
Also, if you want to keep your grub configs, you can copy them to some external storage to not lose them after the installation.
