Please please hep system keeps going to startup repair

This morning my laptop suddenly restarted when it started up. Now Comodo is not recognising my password and keeps going into startup repair.

The password is correct and the laptop I am using is HP Pavilion DV6. The system has the full encryption set on it to avoid personal data being accessed if laptop is stolen.

I have spent hours with no luck. Please please help I have not made any backup`s of files and it is only at times like these you can kick yourself with the biggest boot in the world for not doing so.

Im actually praying to god I can have one more opportunity to backup my files.
