I was having this same error on an e-machine model A26EV17F. At the very end of the ghosting process I was receiving two errors:
(title bar) "Error"
(message body) "Cannot open ghosterr.txt"
This error was followed by
(title bar) "Application Error 437"
(message body) "Cannot read from file If this problem persists, contact symantec Technical Support at »service.symantec.com"
After scouring all the tech support forums I some how decided to try inserting a floppy disk half way through the restore. This time the errors did not show up. The system restored without any problems.
So try inserting a floppy disk after the restore starts. Then remove the floppy disk once the system prompts you to remove the restore cd's and restart the system.
Hope this helps.
