When I download the ISO file my system shows the file as a zip file and not an ISO. I have tried to burn the file as an image to a DVD but my laptop will not bootup from the CD. Settting in the BIOS are ok so I guess the problem is with the ISO file or the way i burned the CD. I have follwed the instructions on the site for downloading and burning an ISO image to CD so I guess that my problem is with the file association in windows Vista. Any ideas and suggestrions welcome Thanks
