I have seen this happen before when you already have had an OS installed on the disk. Try booting in to recovery mode through your installation media, use CMD and use this command, "diskpart" after that goes through use the commands in this order 1. "list disk", 2. "select disk 0", 3. "clean", 4. "exit" 5. "shutdown /s". This will take your disk and clean all of it partitions, data, format and all. it will be just like the day you got it.
