If you are having windows then use Universal-Usb-Installer to create bootable usb stick, and make sure its does not show any error.
If you are having Ubuntu then search is dash for Stratup disk creator and follow the steps here
After making Bootable Usb Stick go to Bios and change its First Boot Priority to usb , and save it ..do restart and it will boot from USB.
