After almost being frustated installing KAOS in a USB, all recommended methods just didn´t work for me, I gave a opportunity to RUFUS ...
fist I created a bootable USB in the usual way with RUFUS. Although the live session worked, when I tried to install to HD, the installation crashed ...
after that, I created a bootable USB using RUFUS but at the moment to write the pendrive I selected dd mode ... flawless !!! not only the live session worked but also the installation ...
I happy to trying the linux flavour that KAOS provides to the user !!!
Well, this is my experience ... I hope it will useful for anybody else !!!
cheers !!
