Here's how to reset your PRAM:
 
Shut down your machine. Yes, all the way down, not sleep or logging out.
 
Press the power button and then press command-option-p-r. ...
 
Hold those keys down until your Mac reboots again and you here the startup chime.
 
Let go of the keys and let your Mac reboot normally.
That failing, try holding down the Option key on boot and go to the repair partition an run Disk Utilities.
Do you have an external Boot disk?
