UEFI - Install Guide - Manjaro
https://wiki.manjaro.org/index.php/UEFI_-_Install_GuideTo use the Graphical Installer select the Install Manjaro option from the Manjaro Welcome screen or from the desktop.. For the ESP (EFI system partition) which will store the EFI Grub binary, a 512mb partition of type fat32 can be created in the partitioning step, and mounted to /boot/efi. If you are dual booting then an EFI partition from a previous install can also be used.
