Hi, Simply edit your GRUB to boot form that specific kernel. Sure, you can: sudo apt-get purge linux-headers-3.X.X-X linux-image-3.X.X-X linux-image-3.X.X-X-generic where you use the actual kernel you want to remove. Look here: http://askubuntu.com/questions/216398/set-older-kernel-as-default-grub-entry Basically you are going to edit your /etc/default/grub And make and do something like: |GRUB_DEFAULT="Previous Linux versions>Ubuntu, with Linux 3.19.0-15-generic"| sudo update-grub and reboot -- Regards
