error while creating the final image of knoppix

[pankajgadhari]

hello friends,
i am also interested in doing some remastering of KNOPPIX, i have followed all the instructions for remastering as documented in the doc section, everything is fine , i have created compressed file system file "KNOPPIX" now the problem is when i try to make the image of the final master CD, by giving mkisofs (along with path of boot.cat and boot.img),(source & destination) it gives me error:
uh oh, i cannot find boot catalog directory "dir_name" (now here the "dir_name" is the directory in which my boot.cat file is present).
i am giving the relative path then also it is giving this type of error.
so plz help me to solve this problem, its very urgent for me.
thanking u friends.
hoping successful solution for this

You must have all the needed files in the same directory, then you must CD into that said directory before you make the final image.
