Surely it must be able to find it in order to install it. I looked in Synaptic, hoping to find where it's located. I didn't find its location, but I note that it has a really long list of dependencies, and there is also grub-pc-bin, one of the dependencies, as well as grub-rescue-pc and grub-pc-dbg.
