Thanks for any pointers
Now I am trying to find a solution to have a dual boot MacMini but NOT having a keyboard or mouse attached. All the controlling should be done through my iPad (with mobile mouse app in iOS and the mobile mouse server running in OSX and Win8). This is probably wishful thinking but who knows if a remote boot manager for iOS exist...
UPDATE: just went through the manual of Bootcamp and indeed seems that one can just set/adjust the 'default OS' in both Windows and Mac Bootcamp software. This does sound that, once installed, a keyboard is no longer physically needed.
Hi Ocean jumper
In order to avoid the need for a keyboard to boot from one OS to another, you can install "BootChamp" in your mac.
it is a small icon on the menu bar that lets you click, and reboot into windows.
Once in windows, as long as you keep your default OS as MacOS, rebooting in Windows will boot back to the Mac.
This creates a process where from the Mac, you click on bootchamp and boot to windows.
From Windows, you click restart and it boots to Mac.
nice and easy, and no holding of keys needed.
