I have an HP Pavilion 423, and I wish to delete everything on the Hard Drive and put it back in the state when I bought it. I notice it has a partition on which all the original drivers and software are stored but the partition looks empty, or rather, all folders in it are deliberately hidden. Now, I've lost any original floppy or CD that might have come with the machine. Usually there's a (red) floppy with which I should be able to start the computer up, and from there format the hard disk and load the OS,software and drivers. Is there any way I can create one of these floppies or is there anywhere on the web I can find a copy? I've tried the hp website but can't see anything obvious. Any ideas please? Cheers.
