i d/l knoppix 3.7. but my question is, do you burn it onto a cd as an .iso image? or do you just burn it on to a cd and put it in your cd drive? im confused on what it means it runs entirely from the cd cuz i burned it as an iso image onto a cd and it opened in ms word. do i have to burn it as an iso image then reboot so my cd drive boots before my hard drive and then proceed to install?
