The original grub.cfg from the old install was correct (/boot/grub/grub.cfg on vda5):
### BEGIN /etc/grub.d/10_linux ### menuentry "Ubuntu, Linux 2.6.31-14-generic" { recordfail=1 if [ -n ${have_grubenv} ]; then save_env recordfail; fi set quiet=1 insmod ext2 set root=(hd0,1) search --no-floppy --fs-uuid --set 4b294ec9-0fb3-44bd-bc61-7f35ccb52534 linux /vmlinuz-2.6.31-14-generic root=UUID=3534fcb7-8b25-4b97-8643-59b566d177d7 ro quiet splash initrd /initrd.img-2.6.31-14-generic } However, the one from the new install put the wrong UUID into the search line: ### BEGIN /etc/grub.d/30_os-prober ### menuentry "Ubuntu, Linux 2.6.31-14-generic (on /dev/vda5)" { insmod ext2 set root=(hd0,5) search --no-floppy --fs-uuid --set 3534fcb7-8b25-4b97-8643-59b566d177d7 linux /boot/vmlinuz-2.6.31-14-generic root=UUID=3534fcb7-8b25-4b97-8643-59b566d177d7 ro quiet splash initrd /boot/initrd.img-2.6.31-14-generic ** Attachment added: "/boot/grub/grub.cfg from the auto-resize installation" http://launchpadlibrarian.net/34569161/grub.cfg -- auto-resize install renders previous system with separate /boot unbootable https://bugs.launchpad.net/bugs/462961 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
