I have been working on customizing a HDD install of Knoppix 6.2.1 for the past several weeks. I have been running into a very specific issue of Knoppix not being able mount anything on a couple different systems that all have a similar setup which I will describe a little later. The output of when trying to boot my HDD install on the primary system in question is as follows:

Code:
Knoppix 6 found at: /dev/sda1
>>> Starting in Live-Mode.
>>> Please do not remove medium until shutdown!
insmod: cannot insert '/mnt-system/KNOPPIX/modules/cloop.ko': Invalid module format (-1): Exec format error
Could not mount /mnt-system/KNOPPIX/KNOPPIX. Starting debugging Shell...
sh: can't access tty; job control turned off
This occurs when using a normal Live CD or my HDD install. I have tested my HDD install and a standard Live CD on over five different computers and they works on all but two. The two computers that have this issue both had Windows as the primary OS (one with XP and the other Win7 64bit) and Ubuntu installed in Windows. The curiosity is that I uninstalled Ubuntu on the XP system and now Knoppix Live CDs work perfectly fine (I couldn't test my HDD setup since it doesn't support USB boot), where before Live CDs would not boot.

Is this a known issue of Knoppix with Ubuntu installations within Windows? Is there a workaround? Thanks for the help guys.
