I'm trying to dual boot my surface pro 2 with kali live linux for pen testing. I've disabled secure boot in the setup, restarted from recovery in the settings section of windows 8 and clicked the usb option that it detects. It only ever restarts though without booting from the usb drive. I've tried the usb drive on my normal laptop and it boots fine. The kali image is the latest 64 bit build from the site.
