I ran update-manager and it (re)-installed grub-pc. The post-install scripts for this Debian package run grub-install to the first available hard disk. It does NOT ask for an appropriate boot disk. So I think that is the source of the problem.
I will try to look into this script and see if I can spot the problem. I am not familiar with Debian packages (yet) but this should be easy to find. -- cannot boot: GRUB error symbol 'grub_puts' not found https://bugs.launchpad.net/bugs/509797 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
