have you read http://www.knoppix.net/wiki/Hd_Install_HowTo
If so did you note that a HD install is not an easy thing to use or figure out? Did you also note the minimum system requirements?

You may not be able to install to a 2GB hda1 since it might not be big enough to hold the entire decompressed Knoppix CD. If it is large enough to allow a complete install, then you will probably have at most 100MB of free space. If I read your hd stats correctly, the HD is 4Gb total? If so, just delete all the partitions, then create at minimum a 2.5 GB hda1 (or use the whole 3.5Gb for root), then 500MB hda2 then 1GB hda3. Format hda1 as ext3. Format hda2 as swap. Format hda3 as ext3. Then attemp to to install.

Its not that easy.
I wish you success.
