Yeah, I've tried with a couple different live media: Talking Arch and Grml. Anyone know what's going on? My suspicion is that the firmware sees that the device has both a standard MBR with boot partition and a GPT partition table with an EFI system partition, so it boots from the MBR first. What's interesting is that when I did the initial install way back in 2012, I did get it to boot the installer in UEFI mode. But that's probably because back then, I had to hand-craft the image on the USB stick to boot with UEFI. I don't remember what I did back then. I lost the image, so I can't compare it to what is being done these days. -- Chris
