    I'm trying to install Windows 7 on my MacBook Pro (15-inch, Late 2011) by using a 16 GB USB. I just finished Bootcamp Assistant, but when the computer restarted I got that error message. I've tried restarting and holding the option key, but the ISO doesn't show up. What do? Thanks : )

    That won't work. You need to burn the ISO file to a DVD and use the SuperDrive.

    My SuperDrive likes spitting the DVDs out and saying I can't use them. Why won't it work?

    Using Boot Camp to make a bootable USB from the Win ISO will work with Win 8 and Win 10.
    I think it is more flaky for Win 7 - doesn't always work...
    You may need to use some other method to create a working bootable Win installer.
    Best plan will be doing that on a Windows PC, using some Windows app to do the job.

    Did you get your Win7 ISO direct from Microsoft?

    Yes I did. I got it through my university (Dreamspark).

    It's in the MacBook firmware.
    MacBooks with optical drives can only install Windows from the optical drive.
    Doesn't matter which installer you use.
    You can thank Apple.

    Here's a possible workaround but I've never tried it.

    Whether or not you can create a bootable USB installer for Windows is irrelevant in this case. You can easily do it with Windows 7 and onward. The problem is an Apple-imposed firmware restriction that prohibits using a flash drive to install Windows with Boot Camp on Macs that come equipped with a SuperDrive.
