How to make a custom ISO of Knoppix 6.7

[ashickur.noor]

... it's all explained step by step on my page "summary.html". In case of error please tell me detailed, what didn't work.

Here is the result of the " kn-prepare" command. I am trying to make my installed knoppix 6.7 with some extra packages from HDD. I am not using virtual box, and I have not put any cd in the ROM as well.

mount: /dev/sr0: unknown device
If CD can't be mounted
please mount it within pcmanfm-filemanager
