Installing Knoppix is never a good idea (IMHO), in this case it is absurd:

knoppix-std is NOT knoppix, it is a tool based on Knoppix. It has been abandoned and is so old as to be nearly useless in any modern context.

It is also so old that it will not support most modern hardware. For example, if you have an SATA hard drive there will be no support for it.

It lacks many things that were later added to knoppix, such as the union file system.

If you want to install a Linux to hard disk, I suggerst Debian, not knoppix and certainly not std.
