You must burn the ISO to DVD so you will also need software that understands what an image is (Windows Media Player does not work); personally, I use IMGBurn.
I have had some success with a piece of S/W I got online called "PASSWORD RECOVERY". You might try downloading it and running it. Instructions come with it. Hope this works for you! ( I cannot include a link to the install. but it can be found at prosoft3d)(right now just $9.95 US)
