Holding SHIFT it appear "GRUB loading." and nothing else. >From a live version I have mounted /dev/sdb1 on /mnt , modified /mnt/boot/grub/grub.cfg and launched update-grub2.
After the restart the same behavior but I noticed that grub.cfg have been overwritten again (as the original one) . Should I modify /default/grub or it is necessary to reinstall grub in the mbr after the modification on grub.cfg not only update it?
