what could i do to fix this problem?
If the partition table has been damaged, it is VERY VERY VERY unlikely that you will be able to recover the current OS install. You best bet is to use a linux LiveCD to grab all the files you need off onto an external hard drive. Then wipe and reinstall windows.

PS this usually happens when the computer is turned off before it is finished shutting down, just saying.
