I don't much about the WIndows 8 installer, but what you say makes perfect sense. In EFI mode grub2 installs most of its files to the ESP, but different distros do different things (part of grub2 in the ESP and the rest in the linux partition). Grub2 does not boot off a NTFS partition, but it will boot Windows off a NTFS partition. There are choices for the format of the ESP but there have been issues when the format is not FAT32. When booting in EFI mode that ESP partition has to be there. After DU loads select your hard drive (this is the entry with the mfgr.s ID and size) from the left side list.
