OK I have spent the last couple of hours trying to figure this out. I have an hp 8200 elite, that will not boot from a USB drive. The drive works fine because I can get it to boot on other devices. I disabled the data execution prevention, still nothing. The device is coming up under the EFI boot section, so I am assuming it has to do with that, but not quite sure what. Any help would be greatly appreciated.
Thanks,
