Windows 2003 does not provides ERD disquete.
The ASR disk is usefull only with a full backup of the system files, created also with the ASR.
You use the ASR and as a sort of "disaster recovery" solution.
The backup of the system state, does in some way the function of the ERD.
If you want to create the ASR disk, copy to a floppy the contents of the c:\windows\repair folder.
Por que hacerlo dificil si es posible hacerlo facil? - Why do it the hard way, when you can do it the easy way?
