The problem here was: I did not create an efi boot partition. But the automatic installer did not create one as well nor complained about the missing partition. I installed manually and it works now.
But the automatic should give a hint at least. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1277865 Title: Cannot install Ubuntu 14.04 on EFI hardware To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1277865/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
