I think that the problem is that its not seeing a bootable disk. When you hold the option key down the machine looks at all bootable drives attached to the system if it finds none It just goes to a blank grey screen with the mouse curser then just sits there waiting for you to insert a bootable drive. The most important thing here is to be sure your partition is GUID partition table for booting intel based macs.
