I have a 21.5" iMac, and I have recently installed Ubuntu on it on a different partition, so i can choose my preferred OS each time i boot the computer. When I installed Ubuntu, it automatically installed some sort of boot menu that allows me to choose the OS i want from a list using the up and down keyboard keys.

Now, I have a standard apple Bluetooth keyboard without a numpad, which works perfectly when booted into Mac OS X and Ubuntu. But in the boot menu, it doesn't seem to respond at all and after 10 seconds I get booted in to the default system (Ubuntu). I would like the boot menu to recognize my Bluetooth keyboard, thanks for any help :)
