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

For the question you mentioned, the problem is

Windows could not start because the following file (\WINDOWS\SYSTEM32\CONFIG\SYSTEM) is missing or corrupt:

and in your case your windows is Windows 7

this problem is exactly the file "\Windows\system32\config\system" may be missing or corrupted and the windows is already have a backup for this file all you need is to copy the backup file to the the current one and restart like the following

  1. Stick in the Windows 7 CD, and boot off it.
  2. Open a command prompt in the recovery console.
  3. go to file location (may be windows appear in d not c because usually there is 100 MB may be invisible for booting) cd c:\Windows\system32\config ren SYSTEM SYSTEM.BACKUP copy regback\SYSTEM SYSTEM
  4. Reboot and remove the windows CD.
