Sorry to bump an old topic, but I'm having the same issue. I bought a copy of Knoppix 6.0.1 directly from the site, so I hope the burning speed/disc isn't the problem. Are there any other possible solutions? I'm running a Dell Inspiron 1520 with a crashed hard drive. Any help is appreciated.

Retroactive, I've sent you a PM.

What actually happens when you try to boot with the Knoppix CD?

me too retroactive ... did you find a solution to this problem? Came home yesterday to find my backup laptop, which is a Dell Inspirion running XP, un responsive. Tried to no avail for 5 hours last night to revive it but no luck. One of my ideas was to run a Knoppix CD i had lying around with at least the hope of retrieving my data. Knoppix acted like it wanted to load, and i saw the penguin and Adrian, then the screen went black and no more. The original reason my OS stopped working was because it says my ntldr is missing, so don't know if that would affect a live Linux disk ...

ntldr is the nt loader, software on the hard disk that is used to boot Windows. Not used by Knoppix, which can boot fine even without a harddisk.

Assuming you don't have another problem, such as a memory problem, that caused the loss of the ntldr, the most common causes of booting problems such as yours are bad burns (often caused by high speed burns and less often by bad media, occasionally by a bad download (avoidable by checking the md5 checksum before burning)), failing or marginal disc drive (try cleaning the optics), or lack of driver support for the drive (for example, trying to run old versions of Knoppix from SATA drives, but unlikely in this case).

thank you for the quick reply. have re-downloaded and will be burning again, this time at a lower speed. the disk i used was one i had downloaded to play with last year. am i correct in thinking that if i can get it to work i can used it to retrieve my data? i know my ubuntu install can see my NTFS (windows) partitions so knoppix would as well? Thanks.

I still haven't found a resolution, no.

Here's a possible fix. I had the same problem with Knoppix 6.4.4 on a Compaq Presario. It appeared that the system lost track of the DVD drive and would only look in /dev/sda1 and /dev/sda2 . The fix for me was to add the noapic cheat code at the boot prompt, then it found /dev/sr0 and booted. So try boot: knoppix noapic
