I'm installing Gentoo and have been unable to get UEFI to boot a live cd or systemrescuecd. When I go into the BIOS and change mode from UEFI to BIOS, I am able to boot a minimal live cd. And from there I used gdisk to create two partitions, the first is GPT (FAT32), and the second is my LVM container.
But then when I go back into the BIOS and change mode to UEFI and try to boot systemrescuecd where I select bootx64.efi which then takes me to a GRUB screen, I then make a selection from there, and the screen just goes blank.
Anyone offer any suggestions to boot UEFI with unsupported Linux flavors on an r920.
