I successfully install Windows 8.1 Pro on my Macbook Air 2013. There is no problem with anything at all and everything works perfectly but one thing is bothering me. When I try to boot up into windows, this screen appears: I wanted my Macbook to boot up straight away into windows and I can't find any option to do so. I do not know why the screen is brought up before I able to enter Windows 8.1 and is there anyway to set this thing up? I can't find any references regarding this screen on google. Hope someone can explain and help me with this. Thanks.
