Yes it has EFI partition which is the first partition, then windows boot, then windows, then others.
I have tried to install bootloader on disk, raid, efi partition. UEFI Bios can see the Ubuntu boot entry but it does not boot there. I have already FreeBSD and Windows booting fine. I have created separate EFI boot partition for BSD. Windows has its own EFI boot partition created by installer which is the first partition on the disk. Maybe Linux installer should also make dedicated efi boot partition when running in UEFI mode?
