Hi, i just bought an UX31A laptop from Asus, but I have trouble booting from the USB device... the device simply doesn't show in the booting list (there's just the SSD containing Windows). The USB ports work well once under Windows, is there an issue with the BIOS not able to handle USB3 Ports ? (since both ports are USB3) This seems strange because the laptop is quite recent... Thanks for your help ! A.
