I am completely new to Knoppix, and any type of Linux at that, and have two questions. First, I am running Knoppix 3.7 off of a cd, and whenever I make configuration changes or save things, it disappears when I start Knoppix again. Is this just because of the CD, or does this happen even after Knoppix is on the hard drive. This brings me to my second question. If I install Knoppix on my hard drive, do I loose any data and can I still use Windows? Thanks for any help you can give me.
