How can I get an existing Vista installation to a "clean" state (without an installation disc)?
I have a Sony Vaio laptop running Vista 32-bit. I'd like to get it to a clean installation of Vista for the purposes of selling it (i.e. rid it of any data). I do not have a Windows installation disc (thanks, Sony!), and the computer does not have a recovery partition. I tried creating a recovery disc by downloading and burning a DVD with the image here, but when I booted from that disc and tried to "install", go an error message ("cannot open the required file D:\Sources\Install.wim. The File does not exist."
