    This could you more clarification. Why am I double clicking on efi? Should I be marking it to be formatted or not? I mark the ext4 / to be formatted. But it still fails. Should the bootload be put in the ext4 partition or in the efi one or neither?

    There are two partitions. The small one is the boot partition, and the large one is for the main file system. The boot partition is set up as fat32, and its where the EFI boot code goes. Ubuntu itself goes into the large ext4 partition. You don’t need to format anything. The installer does that.
