Thanks for teh info on unetbootin but its not doing what i want but it is a neat program and will use it in the future. It took my iso and put it on my usb drive and made my usbdrive an install drive insted of installing it to my drive. Which im sure i'll use at a later point so thank you for bringing this to light.
I have been to pendrivelinux and been over the info there with no luck.
And my bios does boot from usb, as noted Knoppix LIVE is the only one ive gotten to work, but im not interested in a LIVE version at the moment, I got teh kids on a live distro im looking to install Mandriva on this USB 8gb ThumbDrive as I would a HDD.
Thanks again for the help please keep the ideas coming
