First, when creating a USB stick with an Arch ISO, you need to create it as a UEFI bootable USB stick. Then you also need to boot that USB stick in UEFI mode when trying to install to a machine. If you do not create a UEFI compatible USB in the first place, you won't be able to boot it in UEFI mode later. However, even if you have a UEFI USB, you can still boot it in legacy support mode (BIOS) and that will not install/enable UEFI support on your new installation. -- Regards, Konstantin
