Error: "system.dat file is Corrupted or Missing" on Windows XP System?

My windows XP system is not at all starting and instead of starting it is returning an error message saying that "system.dat file is missing or corrupted". I have searched in many sites to find a solution but I couldn't fix it. What should be actually done now to fix this error message? Hope you respond soon.

You can open another "hive" with regedit.

1. Start regedit.
2. Select the HKEY_LOCAL_MACHINE root key.
3. Go to the menu "File->Load Hive..."
4. Choose the DAT file for the registry you wish to edit.
5. You will be prompted for a name to load the hive into. The name does not matter. It just loads the registry hive into a subfolder using the name you provide.
6. You can then edit the registry you just loaded in the same manner as any other registry. All changes are made in real time, just as normal.
7. When you're done, go to the menu "File->Unload Hive..."
