Hi, I am trying to install Windows 8.1 on my Macbook Pro (Retina, 13-inch, early 2015, El Capitan). I have the 64-bit ISO file, and loaded the boot camp assistant app to do the installation process. It was able to partition my hard drive, and after that it attempts to restart in windows. However after a little bit the blue screen with windows icon turns into a blue screen with a frowny face emoticon and a message saying "Your PC ran into a problem and needs to restart. We're just collecting some error info, and then we'll restart for you". After about a minute, my computer reboots, but in the mac OSX... How do I complete the Windows installation?
