Hi! I am trying to install windows 7 on my 27" mid 2011 iMac. I have changed the 1TB HDD with 2x 250GB SSD drives instead. And now i cant install windows 7. When my iMac restarts to get to the windows 7 installation from either my USB stick or CD with windows on it, it says: "No bootable device -- insert boot disk and press any key". I have googled like crazy, and tried different solutions, but with no luck. I have changed the info.plist in different ways, tried installing Windows on both my SSD in my iMac, but nothing work. Can anyone help me with a possible solution?
