I am trying to install Ubuntu 16.04 onto my laptop, which doesn't have a disc drive, so I tried to boot from a live USB. I have followed several tutorials, used various different programs to burn the ISO to my USB, and even searched the all knowing google, but my computer still wont boot from it. I was able to get it to recognize my USB only once in BIOS, and even then it still completely ignored my USB and booted to windows, after I set the USB as default booting priority! I also tested this on my desktop, and a windows 7 computer, all with the same results. Is there a setting in windows I need to disable? or did I just make the USB wrong every time?
