I am trying to install windows 8 on my macbook pro I bought Saturday (2/28). I get past the first 3 steps but when it restarts my computer the first thing it does is boot to the usb drive called windows where it tells me there is no boot disk available press any key to continue, then there is the efi boot i believe which when clicked under boot menu at start it starts to install windows all the way till I have to choose a partition and it comes up with this error message. Please help need windows to run certain programs for school!!
