How do I to remove or hide old kernel versions, to clean up the boot menu?

When my computer initially boots up it lists about 8 different options. How can I clean this up to limit my selection to only one, the current installation?

At one time I was able to clean these up via Synaptic Package Manager but now when I type in the version number (ex. 2.6.35-25) for SPM to locate I can't find them to delete. Is there another way to do this?

Solution

You can edit your Grub entries.

Open a terminal and type:

sudo su
gedit /boot/grub/grub.cfg

Find the lines that start with menuentry 'Ubuntu ...

Each of these lines is one entry of your Grub. To clean your Grub simple comment the lines corresponding to the entries you want to hide.

Comment them with the # character at the beggining of the line.

A commented entry will look like this:

#menuentry 'Ubuntu, con Linux 3.2.0-25 ...

Save and reboot.

@Anwar It's definitely a dupe of that one, but the title makes it difficult for some users to find. I'm going to edit the other one to make it more search-friendly.
