I have two Linux partitions, each running Ubuntu 12.04. One I was using as a legitimate partition for all my real computing. The other I was using as a honeycomb and a fallback partition. However, while working in the legit partition, I was apt-get installing and removing and I must have accidentally included a * or something. The kernel ended up being removed. When I rebooted, GRUB only listed my honeycomb kernels, so now I can only boot to the honeycomb. I was messing around with Cinnamon and GNOME and trying new things out and I got carried away.
The entire filesystem from the legit partition seems to be intact, and the /boot directory had only a grub folder in it and a memtest file.
How can I install a kernel into the legit partition, FROM the honeycomb?
