Abort: 15121, read bios parameter block, unknown fat type ..

Can't get Norton Ghost 2003 to run on 5100 Dell Inspiron Notebook -
Abort: 15121, read bios parameter block, unknown fat type


Ok Ghost worked the first time, but after that it stopped working.



All I get is the following error message:



An internal inconsistency has been detected

Abort: 15121, read bios parameter block, unknown fat type.



Please can some one tell me how to correct this error?



thanks

Jon
