sidelogic

Hi guys, I need help. I could not find any way to solve it. I have trouble with setting up. I am using a Casper Nirvana (i7 3 with 1TB hard drive and 16GB RAM) and I wrote many distributions to many USBs, but the Casper didn't see the USB in BIOS. I cannot find any way to solve it, and I also tried to update my BIOS with USB, but it didn't see the USB again. What should I do? btw i try to setup mint,xubuntu,lite,Debian and fedora
