so um, here is what i did

1)i booted up the computer with the cd
2)it tells me a bunch of stuff
3)i typed "knoppix testcd"
4)it checked a bunch of stuff
5)it booted knoppix
6)i downloaded firefox

Is there any way to uninstall knoppix and its files entirely, because it seems to take up about 10gb of my harddrive :/
