What EXACT model MBP do you have and what OSX is installed.  Your MBP cannot locate the OSX.

Ciao.

I have the same problem, trackpad works but won't click, mouse does not work and screen keeps blinking along with the spinning cursor. I tried the keyboard and it didn't work. I am running a Macbook (2008) the aluminum version with OSX 10.9 Any help would be greatly appreciated.

In regards to the trackpad, examine the battery which resides underneath it to see if it has expanded.  that may the the problem not 'clicking'.

Here a couple of troubleshooting documents that may assist you in finding a solution:
