Thanks for your report.

You've removed grub on the 2008-10-08

Then when you've installed the latest kernel the installation failed with the following error:

You can reinstall grub to workaround this.

A user can remove grub because it's only a recommend and not a dependency of the kernel.

Thanks again for your help to make Ubuntu better.

Yes, I removed grub, because grub on another Ubuntu installation (Hardy) is managing the boot environment.
