AFAIK you can't boot from a logical volume.
You need to remove /boot from vg-g1, shrink the volume-group and then create a regular boot-partition.

Grub2 supports LVM /boot. I would be astounded if Debian doesn't have this documented.

What do you mean by "now i have to reinstall grub" ?. Re-install the entire package, or update the MBR, or re-fresh the config file or something else ?.
