Based on what's said in comment #3 I suspect that there is an EFI System Partition on both the Windows drive (which was disconnected when boot info was gathered) and the Ubuntu drive. That becomes problematic and really is just a limitation of UEFI in itself. I still frequently run into problems with UEFI that require I ask a question at Ubuntu Forums and wait for oldfred to get me straightened out.
