I'm trying to install Windows 10 on my Late 2014 5K iMac. Boot camp copies the files to the USB on the OSX side, and then I partition the HD. It then restarts right back into OSX, I have to wait there and hold OPTION and tell it to boot into Windows. It then starts to install Windows, and I can get to the Windows desktop. At which point boot camp installs the drivers, but it gets stuck at the audio (Realtek) drivers and stays there forever. I have to restart, and then Windows starts up normally, but I don't have audio, and later, things like are not working right. For example, menu items on the START menu are scrambled and illegible. Any ideas? I've tried reinstalling (erasing the partition) twice with the same results. Thanks!
