My question is how can I reverse back to a kernel version. I have installed the brand new kernel version, that is 'Ubuntu, with Linux 3.4.0-30400, I did the correct procedure. How to Upgrade Kernel Version?. But when my machine booted with the new kernel, by the grub boot screen as I clicked, it does not load the operating system. It get's stuck at the boot process. After this event I went to a previous version, that was the default, 'Ubuntu, with Linux 3.2.0-39-generic kernel.' It works correctly. How can I get this working kernel to boot up in the first place kernel, and change the default kernel, to one that works. If you can please explain/instructions, I would appreciate it. Thank You Pictures Kernel Versions Kernel Boot

sudo apt-get purge linux-{headers,image}-3.4.0-30400-generic linux-headers-3.4.0-30400

will remove the offending kernel, so the old one will boot by default.

if you would like to try a mainline kernel this makes it easy to install them
https://github.com/GM-Script-Writer-62850/Ubuntu-Mainline-Kernel-Updater#readme that installer can be used to make a un-installer also

KernelUpdateChecker -k -r precise -v 3.4
/tmp/kernel-upgrade --uninstall
