using the live cd, i mounted my original dapper /boot (which lives at /dev/sda1) into /mnt, and edited my grub/menu.lts, added an entry for my knot2 system and it booted ok.
I also tried to install without formatting my /boot partition, but the installer refused. is there any particular reason for this? it would be interesting if the installer could simply use the old grub, and just add its entry into menu.lst, or at least backup the menu.lst into menu.lst.old, and replace the original with its own. then the user's old grub conf can still be recovered... -- I was trying to save my grub installation in (hd0), so i tried to install it into (hd0,9), ie sda10, my / partition, and the installer crashed https://launchpad.net/bugs/61649 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
