there's no problems with the cd now. I used nero like you suggested and made a new cd, i can boot from the cd.

There is a Knoppix screen which is blue, when it says

Boot:

with the option of entering boot codes... maybe i need some boot codes? because it's AFTER i press enter... 2 files are loaded

like "filename...................." and then another "filename...................."

then the screen goes blank... nothing visible at all. I can hear the Cd spin but eventually it stops.

This is all without use of floppy disc.

hope this clears it up a little
