How to remove the unwanted entries from the boot menu?

I want to limit the number of kernels shown in my boot screen to say only the two latest ones. How can I do this with the new grub? (Any method that does not require manually uninstalling all extraneous kernels is also welcome.)

You'd need to remove the individual kernel images you don't want. I have every kernel starting with the one packaged on the 10.04 LTS disc up to the most recent one (including the backported kernel). There's no automated process to remove old kernels, so you'd have to remove each individual image from your system using Synaptic or some other package manager.

A detailed procedure for removing old Linux kernels and cleaning up Ubuntu's boot menu to use just the latest and next most recent kernels is provided in a series of recent posts starting with GRUB2 revisited.

While the procedures listed in the above are all manual, one of the web references listed refers to a number of graphic tools that may be useful in modifying the boot menu. The specific article is Customise Ubuntu with GRUB.

Legacy GRUB had a variable in memu.lst called HOW_MANY which was how many kernels to retain which took care of this for you. One of the many legacy GRUB features we have lost. I have no idea why GRUB2 does not support this.
