Congratulations, you destroyed your hard disk. Your only option is replacement. I highly suggest getting the Sandisk Ultra 480GB, it's currently on sale for ~110.

After you buy and install the disk (read your computer's manual), follow the instructions at http://windows.microsoft.com/en-us/windows-8/restore-refresh-reset-pc to reinstall the OS
