IIRC, you can select a "image recorder device" in the recorder menu but thats probably not what you want as it will just cause nero to create another image of off the knoppix iso image you just downloaded. "burn image" really should be in the "file" menu! So if you find yourself with a cd that only contains a huge "Knoppix_version_date.iso" file then you got it wrong. There should be a couple files, directories, docs, faqs and so on.

Well, you could pull the plug on your hdds provided that you have a half-way descent machine with, say, about a hundred megabytes of ram. But, you don't have to do this since knoppix will _not_ write/delete anything from your disks unless you instruct it to do so!

I suggest you to not write anything to a ntfs partition as it _will_ (in most cases, even tried it myself) inrecoverably destroy that partition, but knoppix defaults to read-only mode anyway so there's really not much to worry about.

Good luck and have fun with knoppix!
