The day that Knoppix does this at boot I will leave this forum and never look back.

You likely need to give one or more "cheat codes" at boot time. These are instructions to assist or bypass the hardware detection process. I've heard other reports of people needing this when they have SATA drives on 4.0.2 but I don't know what code you need. You could read the cheat code section in the wiki, search other forum posts for others that have had problems booting with SATA drives, or just hope that someone who knows the answer will respond to you.
