    Hi guys, I'm in a right muddle.

    I was trying to boot camp. I followed all the instructions with boot camp assistant, then clicked install.

    My MacBook restarted and straight away a black windows screen comes up and says No bootable device -- insert boot disk and press any key.

    The USB I used to create the windows 7 bootable disk is inserted, pressing any key doesn't do anything.

    I can't even boot back to Mavericks. It's a retina MacBook Pro. I've tried holding shift on start up, does nothing. Tried holding option, does nothing. It's like my MacBook has been bricked.

    Anyone got any suggestions?

    Update.

    Okay, for some reason, after restarting about 10 times, it's decided to boot OS X.
