"the installation routines on the recovery files are going to prompt for you to authenticate the installation S/N"

I think he means an image of C:\ onto CD and straight copy it back after a format and fdisk partition as a DR scheme. You shouldn't need a full install of DOS after a format to run fdisk. Or would you have to format and fdisk with the OS that is going to be copied to the drive? Would there be version problems?
