I am trying to install windows 7 using bootcamp on my Macbook Pro running Yosemite. Everything goes well except when it is done with partitioning the hard drive. When it boots to windows a black screen appears with the message "No bootable device insert disk and press any key." When I press a key nothing happens. I tried restarting it and holding down the option key but only the Macintosh HD appears.
I now burned the iso file to a dvd but when i try to boot into Windows it gets stuck on "windows is loading files." After that an error message appears.
Here is a picture:
