Hi Skippy, You probably need to run “sudo update-grub” which will regenerate your config file & should provide the menu. Any persistent changes you want should therefore be made in /etc/default/grub first. Afterwards, if your 'buntu system is grub2 you could usefully run update-grub from there too. If it is a grub1, then you probably have an entry for Debian in menu.lst something like title Debian (Direct) root (hd0,5) kernel /vmlinuz root=/dev/sda6 initrd /initrd.img To boot via grub 2 needs another entry like title Debian (Grub2) root (hd0,5) kernel /boot/grub/core.img boot Note that partition numbering scheme changes in grub2, it starts from 1 instead of 0. "grub-install /dev/sda6" Will not work, there is only one MBR on a disk, not one per partition. "grub-install /dev/sda" will update the MBR to boot the system you ran the command from, but I don't suggest trying that until UR really sure that grub2 is working OK, and preferably you have some backup boot-able media in case it all goes pear shaped.
