I have a Mac Mini with Windows and OS X installed on it. The Mac is connected to a KVM and the keyboard that I use is a regular PC keyboard. When I try to load the Startup Manager by pressing the Option key at startup, it fails and loads directly into OS X. I believe that the KVM is giving me trouble but I can't get rid of it (I use several machines).
Is there any way that I can FORCE the Startup Manager to load every time I reboot my Mac Mini? If not, can I install Grub in order to select which OS I want to load? Any other suggestions?
