In terminal:
dpkg --list | grep linux-image
sudo apt-get purge <name from previous output>
These steps generally work for me, first make sure you boot into the desired version of the kernel you would want to remove:
rm /boot/{config-,initrd.img-,System.map-,vmlinuz-}`uname -r`
rm -rf /lib/modules/`uname -r`
sudo update-grub
reboot - this should not reboot you back to the previous version of the kernel
