When you use NTBackup (Start / Programs / Accessories / System Tools / Backup) and press Emergency Repair Disk on the Welcome screen, or use the Tools menu to press Create an Emergency Repair Disk, an ERD is created than contains:
<b>autoexec.nt</b> - from the <b>%SystemRoot%\System32</b> folder.
<b>config.nt</b> - from the <b>%SystemRoot%\System32</b> folder.
When you run a System State backup to a file, it also copies the registry files to the %systemroot%\repair\regback folder. You can then create an ERD by copying the 3 files to a floppy disk.
NOTE: If you don't want to save the System State backup file, just delete the <FileName>.bkf file.
