I downloaded version dban-2.2.7_i586 and copied the unzipped version onto a CD. I changed BIOS settings to boot from CD. But, I've tried severall times and it never boots from CD.
Sony VPCCW21FX running on Windows 7.
Check the CD and make sure you see about 6 or 7 files on it. This will make sure the zip file was extracted into several files when you copied to the CD.
