First of all Kon-Boot was not designed to boot from USB sticks. And currently i have no plans nor time for implementing such feature. However there are some methods you can try in order to boot Kon-Boot from USB, check following tutorials:
However i am afraid it will not work for all of you.
Additionally many people noticed me that Kon-Boot was featured in multiple websites and shows like: Hak5 Episode-518, PaulDotCom Security Weekly Episode-158, WindowsITPro, ZDNet Asia, Mega Leecher, and so on! That's cool it would have been even cooler if some of them were able to spell my name right *grin* :-)
