After I upgraded, the grub menu.list file was incorrect. The entry for 2.6.20-15 looked like this BEFORE:
title Ubuntu, kernel 2.6.20-15-generic root (hd0,1) kernel /boot/vmlinuz-2.6.20-15-generic root=UUID=6430bdad-99af-4e51-8552-4f50510924c1 ro quiet splash initrd /boot/initrd.img-2.6.20-15-generic quiet savedefault AFTER the upgrade, my 2.6.20-16 AND 2.6.20-15 entries were altered so that neither was bootable. The offending line seems to be the "root" line as it was changed to "(hd1,1)" instead of the previous "hd(0,1)". I manually adjusted this and was able to boot BOTH 2.6.20-15 and 2.6.20-16. After upgrade: (before I manually fixed it) title Ubuntu, kernel 2.6.20-16-generic root (hd1,1) kernel /boot/vmlinuz-2.6.20-16-generic root=UUID=6430bdad-99af-4e51-8552-4f50510924c1 ro quiet splash initrd /boot/initrd.img-2.6.20-16-generic quiet savedefault -- latest kernel(2.6.20-16.28) update gives boot problems https://bugs.launchpad.net/bugs/117314 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
