Can't Boot off of Pen Drive on a Dell Turion 64

[kl522]

I am a fan of Knoppix.

By any chance you have another copy of KNOPPIX ( different version ) residing say on your harddisk ?

The error usuallly means the cloop module found on /dev/sda1 is not compatible with the kernel. On my computer, sda1 is my harddisk partition. My flash is sdb1.
