Not knowing what sort of hardware you are trying to boot, I will point you to the documentation link at the top of the page. Look for the "cheatcode" link, go there and read it. There may be one or a few cheatcodes that can help you boot Knoppix. One to try might be "knoppix xmodule=vesa". These are entered at the boot prompt. Once you have booted successfully you can then proceed with whatever adventure you desire. Keep in mind that writing to an NTFS partition using Linux can be a risky procedure and can result in data corruption and/or a permanent loss of data. I would strongly suggest that you FIRST back up all of the data you can recover BEFORE attempting to make changes to your drive.
