    how to add dual boot to Windows 10

    new around here, so hello everyone ....

    Just got new desktop tower with Win 10 Pro on it. Added two old drives to it, one with XP pro, and one with Win 7.
    Wanted to have multi-boot option on it, like I had with the old machine, but Win 10 loads right away, w/o giving me option to choose.
