I've tried making a USB flash drive from Knoppix 7.05 but I can't get the drive recognised (to boot from it - I can see the drive in OpenSuse) on 2 out of the 3 computers I've tried. On the 2 it fails on, it does not show up on F12 for boot menu or on listing the hard drives in the BIOS settings.

The PC it works on is an AMD dual core with a FoxConn motherboard.

I can't get it to work with my Fujitsu Siemens Li1705 laptop and my desktop PC which has a Gigabyte GA-970A-DS3 motherboard which now (I've just updated it - hoping that might fix it) has the latest (30 Dec 2012) BIOS installed.

I have tried two flash drives, a 16GB ByteStor and a 32GB Transcend Jetstream with the same results. Both of these drives will boot an OpenSUSE 12.2 Live KDE CD image on my desktop PC (I didn't try the laptop).

I have tried both the Koppix CD and the DVD installs following the on screen instructions.

Any ideas?
