Solved. The installer has a bug. I have a separate boot partition which the installer did not mount or perhaps unmounted (it is in /etc/fstab)
Anyway: * The new kernel was installed in the mountpoint directory. * The initrd image was missing from the grub menu.lst * The hd(0,0) line was wrong Running grub-install did give an error, so I expect it also gave an error on install which could have been caught. -- [hardy->ibex upgrade] system is now unbootable https://bugs.launchpad.net/bugs/291264 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
