Hello and welcome Atleast mate looks like quite a pickle you are in. Now two scans we would normally ask you to do are these if you haven't run them already

http://www.sevenforums.com/tutorials/433-disk-check.html < if necessary include the /f and /r in the command line as per Option2
If these do nothing then post back please but just make sure you run them as admin and in safe mode if you want to as safe mode only loads the essential Windows files to power up. To do that shut down then wait a few seconds - power up while tapping F8.

Hello Atleast, and welcome to Seven Forums.

In addition, you might also see if doing a system restore at boot using a restore point dated before this happened may be able to undo and fix this for you.
