    Can I install windows on an external drive?
    can I install windows on an external drive and have the choice boot from it when I need to do something windows specific, by selecting it as a start up disk? I don't want it on my machine at all times, but there is a time I'd need it and I don't want it to take up space on my internal hd.
    if it's possible how is it done? I have a windows vista disk, and an external HD ready to go.
    Thanks.

    Specs:
    Late 2013 27" iMac, iPad 3, iPhone 6s+, iPhone 6+, 3 iPods, Sierra
    In short, no. MS has restricted the installation of its Windows operating systems to internal hard drives only.

    Back to my old 2.2GHz C2D MB after selling my MBP and wondering what my next Mac will be :)
    Running it on Boot Camp, you aren't looking at taking up much HD space anyway.

    See here for different Windows OSs
