Ok, I added all the info, I hope it helps. I took the liberty to add a couple more useful outputs.
My computer boots from /dev/sdb , but I always keep a grub in /dev/sda just in case. Both of them failed to load grub after the upgrade (I only run grub-install > /dev/sda every once in a while, I only do it since I started hitting this bug). I have been running Kubuntu for ... 2 years now on this computer? So there are several layers of upgrades, and there is certainly the possibility that an old setting is bothering things, as Colin stated. @ Frank: I showed the commands I ran on the command line to generate teh attachments, in case it helps. @seasoned_geek: please note that this is not a forum where users exchange _opinions_, but rather a bug tracker. Even when you are trying to help, you are introducing noise, which actually hurts the chances of getting things fixed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/496435 Title: upgrades of the grub-pc package can overwrite wrong MBR -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
