    I'm trying to install Windows 7 Professional 64-bit on RMBP from USB.

    i'm getting an error

    "Setup was unable to create a new system partition or locate an existing system partition."

    Hope someone can help me. I've spent hours trying to figure this out, with no luck.

    There should be a partition called "Bootcamp", you need to format this partition during setup.

    Basically when it is asking where to install windows, there should be a button that says either 'format' or 'erase'. Click that & select the bootcamp partition.

    You should then be able to install to the partition.

    Hope that helps...


    ALSO make sure you've removed any external hard drives you may have plugged in.
