booting from cd and thumbdrive problem

[Werner P. Schulz]

First of all test your download like this example

md5sum -c KNOPPIX_V6.7.1CD-2011-09-14-DE.iso.md5

Test the burned CD with

md5sum /dev/sr0

or start CD with cheatcode

knoppix testcd

.

How did you manage the flash disk installation? With another CD?
