The installer detected the EFI/recovery partitions on your old drive and reused them. It's one of my biggest annoyances with Windows because it means you NEED both drives to boot. Users end up in this state all the time without realizing it. Recommend removing all drives except for desired boot drive and reinstall Windows.
