A. The problem is a bug in Win2K Backup’s ERD-creation process. If a system’s \%systemroot%\repair folder is empty (because you moved or deleted the files it contained) when the process launches, the bug prevents the creation of hard disk-based copies of the registry files and the 3.5” ERD. To complete the ERD creation process, you might need to restore the files to the folder temporarily-using copies you originally made from that system or that you make from another system.
