I have recently updated my kernel version. I restarted my computer and this is what I get!

enter image description here

I have installed the version 'Ubuntu, with Linux 3.4.0-030400 version. When I click enter with the first choice. My machine boots to the version but after clicking the new version, my screen stays purple. I restated my machine, went to the grub screen then to the 'Previous Linux Versions', then went back to my previous kernel version 3.2.0-39-generic' and runs correctly and works perfect.


Previous Kernel Versions

enter image description here

How can I delete this new kernel and get the previous one back? Can I restore to an older time, with the good kernel? Can I delete all the kernels and put this new one in?

Do you want to remove the 3.2.0-40 entry? – thefourtheye May 1 '13 at 14:18
I want the previous version, and get rid of the new one. Yes – Ronnie Marlow May 1 '13 at 14:25
please add the output of the following command ls -ltr /boot – thefourtheye May 1 '13 at 14:26
Thank You for the help. I'll try it out. – Ronnie Marlow May 1 '13 at 14:31

I would advice you to use Synaptic to uninstall it, unless you're comfortable with using the Terminal. So please install Synaptic:

sudo apt-get install synaptic

When done, run Synaptic like you would any other app. In it, click on the Status button in the lower left part, then select Installed in the upper left part of the screen. Search for linux 3.4. Delete any packages that have linux-headers or linux-image in their name and are labeled with version number 3.4*. Restart the computer.

If I may notice, you should also delete any kernels older than the one you're using (3.2.0-40), because there's no need for them, and they can really take up your HDD space. To remove them, you can use the same method as for 3.4* and just changing the version numbers, or you can install Ubuntu Tweak tool and delete them all at once from the Janitor tab.

The solution of my problem was going around the kernel. I used a program called 'Grub Customizer'. The details that you gave me still, was done. But did not work. Thank you for the help. – Ronnie Marlow May 2 '13 at 19:40

My system crashed in the middle of an upgrade and after reboot my kernel was hosed. Because i'm lazy, I remember boot repair which i've used in the past to fix grub, it has an option to repair the kernel.

Boot from live cd and:

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair
