wslkevin: Before you go any further learning GRUB,

a) what version of Knoppix are you using? and
b) does your computer have a CD-ROM drive? and
c) are you trying to boot the ISO from an NTFS partition?

Because if you're trying to boot to the ISO using the files from "regular" Knoppix, you won't be able to boot without your computer having access to the Knoppix CD.

Why? Because Knoppix first boots using a compressed file system ("minirt24.gz" or "minirt26.gz", depending on which kernel you're using) that doesn't include the NTFS driver. It has to get the NTFS driver off the CD.

Now, if you have access to the Japanese edition of Knoppix (or simply its kernel and modified miniroot), you can. They included the NTFS driver in their miniroot and modified the startup script accordingly.
