    I recently just purchased my rMBP and installed Bootcamp ( Windows 8 )on it today .
    After it restarted , it showed a White Screen for 5 minutes and then says " No bootable device - insert boot disk and press any key "
    I already have a bootable Pendrive plugged into it and it still says the same .
    It wouldn't boot Mac up also .
    What should I do ?

    Hold down the OPTION/Alt key right after pressing the power button to get to show you all connected bootable devices and be able to select one of them.
    Your Windows install is probably toast, since it is not officially supported yet, but the rest should be fine.
