    Hey guys. I am trying to install Windows 8.1 in bootcamp on my 2015 15" retina MacBook Pro. It partitions fine, and I choose the ISO, but when it reboots to start the Install, I get a flashing folder with a question mark. I've tried a few times with different ISO's, same result. Does anyone have any idea how I can fix this? I am on the 10.11.3 beta.

    The flashing question mark means it failed to find any boot device. Did you try holding down the option key while the Mac boots up? That will give you a list of bootable volumes to select.
