Unable to boot into safe mode

help! my macbook is doing something new and strange yet again. when i turn my computer on it brings me to the login screen but instead of my picture there is a pcture of a silloute with a question mark inside. instead of my name it says '[update needed]'. when i put my password in it shows the apple logo the goes right back to the login screen and imediately freezes. it wont bot into safe mode and holding the option button reults in a picture of my hard drive with no other options. someone please help me im wracking my brain!

 

I have a 2011 macbook pro. thats all i can tell you at the moment as I cant get to but 2 screens. command + R only brings me to a screen with a picture and name of my hard drive. all i can do from there is click on it to go back to the messed up login screen or connect to the wifi. btw im running Mavericks. thanks so much for the reply!
