I have copied a knopix cd from my friend. But unfortunately the cd was not a bootable one.I have already copied all of the contents and when I run from windows it works fine.

How can I enable the bootable option to the cd now ?

I am using the nero express for burning.

Thanks in advance for any answers.

You just can't.
Even if the cd session is not closed, you can add datas, but not those necessary to transform it at a boot cd.

The price of a cd is so low that you really better have to burn another one rather than searching for an hypothetical workaround.
