When i got home today and turned on my server, it didn't turn up on the network so i plugged in a keyboard and monitor and found the following error msg "this is a freenas data disk and cannot boot system. system halted".

I restarted it a few time and still kept getting the error msg so i turned it off and went to bed. when i got up i turned it back on and got this error msg "Reboot and select proper boot device or insert boot media in selected boot device and press a key".

Dose anyone know whats going on with it and how to fix it.
