Took a look around to see if there was any information on that error, and found a few things for you. Most of the steps are for Vista and Windows 7 - if you have a different OS loaded on that Mini, please post back anytime to let me know.
I also found this link, it might help as well: Resolve Boot Device not Found Error Message
Good luck, and let me know how it goes
