symbolic links are commonly used in /boot so fat32 is probably not the best idea. > /dev/sda3 volume group vg_jab (left 100MB unallocated at end) > lv_mintroot 8GB / > lv_mintvar 4GB /var > lv_mintswap 2GB [swap] > lv_minthome 80GB /home > lv_mintgis 1000GB /gis > 4.

You do not say how you install bootloader. If you are using distribution specific scripts you may have better luck on corresponding list. In general "grub-install /dev/sda" should figure out what drivers are needed to access /boot/grub and include them in image. If /boot/grub is on LVM, grub should include drivers for it in image. It is impossible to say what is wrong without knowing exact procedure how grub was installed. > > I am looking for advice on what might be the best approach to take now.
