You try to install Ubuntu in UEFI mode, but you do not have an EFI-System-Partition.
But if you have Windows installed on disk, you will not get a working dualboot. For a working dualboot, you have to install Ubuntu in BIOS mode.

If you like to install Ubuntu in UEFI mode, add an EFI-System-Partition.
If you like to install Ubuntu in BIOS mode, you have to start your installation medium in BIOS mode.
