I executed the following command from a Ubuntu live cd terminal (dont ask why).

 dd if=/dev/zero of=/dev/sdb2 bs=512 count=1

Where sdb2 is a NTFS partition (third partition) on a disk. Suffice to say it is now messed up. When I boot into windows 7, it does show me E drive but when I click on it it asks me to format it.

I am not ever sure what I did, did I mess up partition table or only the MFT? Is there any way to get the data back>

PLEASE HELP! this is very important :(
