Dual boot. Ubuntu update removes Debian GRUB. Hello Debian support,
Last week I installed a few updates to Ubuntu 14.04. It installed the updates and then froze whilst installing Ununtu's grub. After the re-boot, Ubuntu was the only choice of O/S. No sign of Debian. After a few hours I finally got Debian recovery to reinstall the Grub on the MBR of the SSD. Some notes. 128GB SSD /dev/sda (GRUB finally reinstalled here) Partions 60GB Ubuntu /dev/sda1 4GB Ubuntu swap /dev/sda8 54GB Debian 'Jessie' /dev/sda7 (unlocked) 6GB Debian swap /dev/sda6 (unlocked) GRUB 4GB Debian GRUB /dev/sda5 (will not boot from this) Ubuntu boot loader is installed here too. Encrypted partitions 54GB Debian 'Jessie' /dev/mapper/sda7_crypt 6GB Debian swap /dev/mapper/sda6_crypt TWO QUESTIONS. 1/ Can anybody explain why the Ubuntu update deleted/removed the Debian GRUB? 2/ Is there a Debian approved GRUB boot customizer? I can't find one mentioned anywhere. Is it possible to resolve this? This would be a pain in the butt, if I had to do this at every Ubuntu update! Thanks for your help.
