I switched to refind and it works beautiffuly, just follow the wiki here: https://wiki.archlinux.org/index.php/UEFI_Bootloaders#Using_rEFInd and set your ESP partition like Mike suggested. The tricky part is to boot the iso into efi mode, it complains about it having no loader config (at least for me). You can work around that if you already have refind on the ESP partition, if you don't, install it in EFI/Boot/ and name the efi file bootx64.efi (be sure that it scans externals, or optical if you're using a CD). You can then load refind by going into your EFI bios and choosing "Load EFI Shell" (note that not all EFI bioses have that option). -- Maxime
