This will be easiest if you have a USB Flash Drive or External USB Hard Drive you can save the files to.

Knoppix can be downloaded here: http://www.knoppix.net/
A tutorial for using it is here (this was written with an older version so the pictures may look slightly different but it is done the same way): http://www.shockfamily.net/cedric/knoppix/

Good Luck!
