First of all, thank you very much. Sorry, I needed the machine, so I re-formatted root partition. I did not preserve copy of the update log either, as Linux was not bootable.
I do not consider this to be related to update process per se. My primary concern were problems during installation process. They are not related to the update: I had the same kind of reaction, when I successfully installed Linux (including Grub), and then decided to change partitioning scheme. Being Linux newbie I used external tool: deleted all Kubuntu partitions, created new, and was not able to boot Live CD. Apparently some component presumes that if MBR contains Grub, the partition with Grub should be this or that. My solution was (in both cases) to zero MBR (except for partition data and signature, which are last 42h bytes). After it, Live CD went up ok, and I was able to install Kubuntu. The only other thought I had is that Grub might place some of its data in MBR, which are misguiding in this situation. Please let me know, and I will do my best to reproduce the problem (with boot, not with update) on other computer. I think I can do it pretty consistently. -- installation failure (grub) https://bugs.launchpad.net/bugs/177951 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
