bootcamp partition is missing
So I wanted to Install Windows 8.1 on my Macbook Pro using Bootcamp. I put the ISO in a USB using Bootcamp assistant and when the mac restarts to Install the windows I get the question "Where do you want the Windows to Install" there I am supposed to choose the driver named BOOTCAMP (according to FAQ on how to install Windows) but I can not find that driver listed and it says Windows cannot be installed to this disk if i choose any other driver.. Please help, its urgent for some school work.. and also in disk utility there is only one driver showing, it is suppose to show Bootcamp there too, no?
Thank you.
MacBook Pro (Retina, 13-inch, Late 2013), OS X Yosemite (10.10.5)
