Remove Old Kernels In Ubuntu

I was asked to do a tutorial on how to remove older kernels from your system to save space.
I'm going to do it but before I go any further I have to post this;

Disclaimer and Warning!!!!
I will not be responsible for any damages incurred to your system by following this tutorial.
It is YOUR responsibility to carefully read and follow the instructions in this tutorial. It is also your responsibility to make intelligent decisions when deciding what kernels you will remove. Removing the wrong kernel version will render your system inoperable.

There! That legal nonsense is done.

The first thing you need to do is find out what kernel version you are using at the moment.
So open up your terminal and type in the following command;
uname -r

You will get a result that looks like this;
2.6.22-15-generic

You can see that I am running version 2.6.22-15-generic

Write that down. Don't depend on your cranium memory because depending on how many versions you have installed, you can become easily confused on what version you are using and may end up deleting the wrong version.

Close your terminal and open up your Synaptic package manager.
Click on Search and type in Linux-Image
Your results will show you all the versions available and the versions you have installed will have a green box in front of those.

Carefully scroll all the way to the end as they are not all grouped together.

Now find your version and make note where it is in the list.
Look through the list for the kernel that is one version previous to the one you have installed now.
You also want to keep that previous version in case something goes wrong with your current version like during an update. That way you can boot into the previous version and try to get things fixed.

Now make note of the remaining versions. Careful! Don't mistake a version like 2.6.22-15.52 as an older version of 2.6.22-14.54

Once you have identified any other older versions in your list you can mark them for removal.
I do want to make a notation here about the packages in the list.
You will see at least one file that looks like the following;
Linux-Image-Generic and to the right under the Installed Version column you will see something like 2.6.22.15.22
If you highlight it, right click and check the Properties you will see it is about 56k in size.
Do NOT delete that file!
It is the header used by the 2.6.22.15 kernel.
Deleting that will damage your system.

Once you are finished removing your old kernels it may be a good idea to reboot the system and make sure everything is working correctly.

Good luck and hopefully you had no problems during the removal of your old kernels.
I fulfilled a request and hope it helps many others.

Edit The Menu

Your Applications Menu can be used to install or remove software by using the Add/Remove link at the bottom of the menu.

And that menu can be customized to add or remove listings and/or category.
You can even add a new menu to the main menu.

Here's how;

Place your cursor over the Applications button in the tool bar.
Now right click on it and from the menu select Edit Menus.
There you will see each category and software listed within it.
Place a check mark next to the software to have it appear in the menu. Uncheck it to not have it listed in the menu.

You can even move a software listing from one category to another using the 'Drag and Drop' method.
One word of caution;
When you drag a software listing from one category to another you are actually doing a Copy and Paste.
The original stays put and a new listing will show up in the category you dragged it to.
So you will need to right click on the original listing and delete it unless you want it listed in 2 categories.

You can even add new categories (Menus).
There are many options and tools available to fully customize the menu to suit your liking.
