Believe it or not, there is some missing info. What other partitions are in use, and for what? And, where did you put the bootloader?

If you have another linux partition, at least at first, install boot loader in Knoppix partition, and go to main Linux distro and tell it to chainload.

Something like this:

root (hd0,1)
chainloader +1

Google for Grub manual version 0.97 and use their format, since most of us don't have that much experience.

For example, ### means nothing to me, though it may be correct. Also, isk means nothing to me.

And, it is normal to put

initrd /boot/initrd on a different line.

And, if Win is present, linux usually starts at hda5.

At a terminal, df will give you some info on where you are, though it only includes mounted parttions, of course.But, do doublecheck it, since many problems are often very simple things, not the highly abstruse.
