BSOD Unmountable Boot Volume

I’ve searched around looking for help with this problem. Most questions were about desktops, not much help for a laptop user. I’m using a Sony Vaio. Last night, I was playing a game and it locked up. I did a hard reset and when I turned it back on, I got a BSOD. ‘Unmountable_Boot_Volume’ Technical Information : *** STOP: 0x000000ED (0x86CCDE30, 0xC000009C, 0x00000000, 0x00000000)

Any help would be appreciated.
