Please don't post the same thing multiple times. This is considered a form of spamming. Your duplicate posts have been removed. Please also use informative subjects, your "help me" subject line was one of the ones that was removed.

The forums are organied by subjects. You seem to have seen that since you posted in multiple foruns. If you really want to discuss installing Knoppix, the best choice for that would be the HDD Install forum, which you did not use for any of your posts. But see below.

Knoppix is really not suitable for installing to a hard drive, particularly not for a beginner. See answer #2 for details.

Debian is extremely compatable with Knoppix (Knoppix is built from Debian). It is intended for hard disk install. So if Knoppix fits your needs, Debian should install and work well for you. That's not to say it's the only Linux distro that might be a good choice, just a suggestion offered in answer to your question.
