And then restart boot repair disc windows 7. Try run CHKDSK x: /f /r via command prompt

Use last System Restore Point or you may try to backup original SOFTWARE registry hive and copy backup from location c:\windows\system32\config\RegBack\SOFTWARE. – week Sep 3 '13 at 6:57

Try installing a clean windows 7 from your windows installation disk , this should solve your problem and will give a clean and cured PC with win7.

The problem is exactly that the file "\Windows\system32\config\system" file may be missing or corrupted. Windows already has a backup for this file.

And in your case your Windows is Windows 7.

All you need to do is to replace the backup file with the current one and restart like the following:

  1. Stick in the Windows 7 CD, and boot off of it.
  2. Open a command prompt in the recovery console.
  3. Go to the file location (maybe Windows appears in d drive not c, because usually there is a 100 MB partition that may be invisible for booting) and type the following commands:

    cd c:\Windows\system32\config
    copy regback\SYSTEM SYSTEM
  4. Reboot and remove the Windows CD.
