Good Day,
I have an iMac which when using bootcamp and reboots. It says at the black screen with flashing white error. When I tried to turn using option key and select the dvd drive myself "theres a efi boot and windows" For the Windows it goes to the black screen flashing white line. Efi just says at the boot selection screen. I tried of DVD Original Windows 7 DVD and also got a Windows 10 USB key same thing. Also got a 7 USB made, even Windows 8.1 USB. All original USB were Microsoft Original installation media. And the Windows 10 USB its the way Windows 10 came.
I even tried to clear PRAM and NVRAM. No difference.
OS X recovery starts fine. Also booting from an OS X key works fine too.
