Can't find Knoppix filesystem

[hellfred]

I have the latest knoppix version 4.2 and I can't boot from the cd. When booting, the following message is displayed:
"Can't find Knoppix filesystem. Dropping you to a (very) limited shell "
I'm using an Intel P4 3 Ghz, 1 GB ram, Asus MB. I've tried deactivating the HyperTreading option, but it still doesn't work. The CD is ok, it worked an a different computer.
Please help.

Do a full test of the cdrom. Eventually other intakt cdrom-drivers etc. where used on the ohter system and on the P4 you try to load defect one
"knoppix textcd"
How do you boot?
What comes ahead of the error message?
Did you try "knoppix 2" or "failsafe" at the first screen ?

If booting without CDRrom at all, i use the Windows Partition PMI.Works even if you only have NTFS partitions.
By the way, with 1 GB of ram and the cdrom-version you can load it all to the ram, too.
"knoppix toram"
