Got my new DN2820FYKH and I'm trying to install the Intel version of Openelec via USB but it won't boot successfully to USB. I have made sure the option to boot fro usb is checked in the bios. I have tried 5 different USB 2.0 removable drives and none appear when I choose the boot menu. My internal sata appears in the boot menu. The USB devices work in another computer. I tried both rear and front USB ports.
When I choose to boot to USB from the BIOS, the computer rebooted and then I think tries to boot from the chosen USB but just rebooted. Happened with all 5 USB devices. The only thing I have gotten to boot is an USB external drive.
