I would first try disconnecting all of the peripherals devices (other than the keyboard, mouse & screen). Are you able to start the system then? If not try doing a SMC reset now. Any difference?
 
The next thing is to start the system in single user mode - Holding down Command-S when you restart.
 
If you have access to a second Mac see if you can boot up in Target mode and then connect your other Mac to your mini to run Disk Utilities to see if something is messed up on the drive. You may want to back a backup of your data first and lastly reformat the drive & re-install the OS.

The problem you are facing here is the boot sectors are messed up! You need a second Mac to fix this. I've never was able to fix a Node issue using Single User Mode. The problem is similar to what you face when you go the the shoe cobbler you need to take your shoe off for him to fix it ;-}
 
Here we need the system to be running off of a second disk (freeing the drive). Or the reverse, use a second system to access the drive which is by far the better way.
