Seems that this issue is related to UEFI, or EFI based system

    When I was playing with boot camp, I found if I inserted any USB devices other than installation media, Windows would report "there is a problem locating or searching installation destination" or other similar description.

    I thought this was an apple issue.

    Today, I do the same thing on a PC, and I get exact same error message as well.

    Therefore, I guess this is the EFI issue, not Apple issue.

    Any comments and thoughts?

    I have connected and used ( W7 SP1 Pro ) and do connect and use ( W10 Pro ) following USB devices with my MBP 7.1 ( USB 2.0 ):

    External Keyboard
    External HDU´s
    USB sticks
    Nikon camera
    RS232 port

    Never had such an issue. I do not use BootCamp 6 ( had a bunch of issues when I tried to install the drivers on this unsupported system ). I use a BootCamp 4 ( Apple Coprocessor & SMC ) / BootCamp 5 ( all other MBP Apple devices ) driver combo, both in W7 and W10.

    I thought it was SOP to remove all USB devices when installing via Bootcamp.

    I had none plugged in during BootCamp installation :) . I think Shirasaki has issues now, with or without BootCamp ( Windows PC ).

    Shirasaki didn't make it quite clear, but was talking about Windows installer, which does not work well with some USB devices.

    Could be EFI related, but mostly it's an issue with the Windows installer, which has a very limited USB support. USB3 devices often cause issues, and basically anything that is not a USB 1.1/2 mass storage device can be problematic.

    Unfortunately there's only one way around the issue: If you don't need to have the device connected during installation, leave it disconnected.

    And this force users copy all necessary files to installation media, rather than plug it in and find it temporarily.

    Talking about USB 3.0, I suspect this may also be the possible reason.
