If you have installed a few linux kernel upgrades, your GRUB menu will become cluttered, with 2 boot options for each kernel, it can quickly become messy. It is easy to remedy though, just uninstall the kernels you don’t need.

For example, Hardy’s current kernel is 2.6.24-18-generic. I also have the 2.6.24-17 and 2.6.24-16 kernels installed, so I have a total of 6 linux entries in my GRUB menu. I have been using the -18 kernel for a while and know that it works fine, so I just uninstall the 16 and 17 kernels. To do this, search for “linux-image” in Synaptic.

You can see the 16 and 17 kernels listed. Just right-click on each one and select “Mark for Removal”. You will then get prompted to mark additional required changes relating to removing that kernel image.

Finish off by clicking “Apply” in Synaptic to finish off the kernel removal. When you next reboot, your GRUB menu will be nice and clean.
