I recently found out I had different kernel versions installed, so I removed the 3.9 kernel as proposed in this answer on my earlier question. After that, I updated my grub, but My laptop won't seem to reach it.

Output of aptitude search linux | grep ^i:

i   libselinux1                     - SELinux runtime shared libraries

How do I proceed to fix this error from my live cd?
