You need to make sure the dvd/usb gets booted in UEFI/EFI mode first, otherwise UEFI install will fail.Boot the dvd/usb, open a terminal and run this command:Code: [Select]ls /sys/firmwareIf you see "efi" listed in the output, then you're booted in UEFI mode and can go ahead with install attempt. If not, then you need to reboot and look for an option that boots the dvd/usb in UEFI mode.

On partition selection page after choosing "Something else", highlight the 550MB FAT32 partition, click "Change" button, then:"Use as" = EFI boot partition, (or similar wording). I believe selecting that will automatically make installer know that the mount point for the partition is "/boot/efi"; but if you do see a separate box for "Mount point" after filling in the "Use as" box, fill-in as seen below."Mount point" = /boot/efi (this step may or may not show -- see above)Keep size as-isHit "OK"Then you should be able to select "/dev/mmcblk1pt1" as "Device for boot loader installation" near bottom of window and grub should install properly.Incidentally, (just for information purposes), attempting to install grub to that partition as "bios_grub" probably failed for one of several possible reasons (most likely one being listed first below):If you're live dvd/usb is booted in UEFI/EFI mode, it won't use a "bios_grub" partition, even if you try to point to it. That partition is only used for Legacy/Bios mode installs to a GPT disk.If you were booted in Legacy/Bios mode for the install (doubtful in your case), that partition needs to be "unformatted", (not FAT32), and the "bios_grub" flag needs to be set on it.In Legacy/Bios mode install, "Device for boot loader installation" should be directed to the MBR of the drive, not to the "bios_grub" partition. (Eg. to "/dev/mmcblk1" in your screenshot, not "/dev/mmcblk1pt1".)
