2014 MacBook Pro Retina Failed Boot Camp Install, Loading Screens During Boot My girlfriend has a 2014 MacBook Pro Retina that we tried to install Windows 7 on through BootCamp. The install failed (I don't remember how... It actually got partway through the install), and since then it looks like there are loading screens (Similar to the "Windows is loading..." screen on the windows 7 install media, before you see the blue background with the installer) during boot.

We have disabled bootcamp and removed the space set aside for windows with the OS X disk manager. Does anyone know what this is, and how we can stop it happening?
Based on the information you gave I can't really guess why, but your Windows install failed.
I would suggest you try again, making sure you carefully follow the instructions in Apple's Boot Camp manual step by step.

Be sure to back up your data before doing so.
