I turned on my computer today and b4 windows opened i was prompted with a black screen and white writing saying that i have not shut my computer down properly (which i do and have been), and it gives me a list of options to choose from:

Safe Mode, Safe Mode With Command Prompt, Safe Mode With Networking, Last Known configurations, and Start Windows.

Now, i have tried every single of of these options and they all bring to me a blue page with white writing, sayin that the computer has shut down windows to prevent it from being damaged.  Under this it says:

UNMOUNTABLE_BOOT_VOLUME

Then at the very bottom it says:

Technical Information:
***STOP: 0x000000ED (0x80EF68F8,0xC0000032,0x00000000,0x00000000)

If anyone knows how to fix this, it would be apreciated.  I am using my laptop to write this message, but i need my computer fixed.

Thnx
