I just did the upgrade from 12.04 --> 12.10 --> 13.04 and got this issue.
I fixed it by the suggestion here, to run grub-install. For my system, I did: > df I found that my root partition was on sda1 - and as I only have one HDD, I know it's sda now. > sudo grub-install /dev/sda > sudo update-grub > sudo reboot More info on installing/reinstalling grub: https://help.ubuntu.com/community/Grub2/Installing -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/733836 Title: "Error: file not found" when booting, then boots up anyway To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/733836/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
