I'm going through the process of installing Windows onto my Mac in order to access applications that are not compatible with OS X or Wine (and also for the better Intel drivers), but the problem I'm currently facing is as follows : I have already partitioned my hard drive before so that I could install Crunchbang Linux, and since that was on Snow Leopard it appears that El Capitan no longer recognizes that as a partition and it refuses to install Windows. I went ahead and created a partition in Disk Utility instead (though it isn't NTFS), and I would like to know what options I have now. I've already used Boot camp to create a Windows installation disk, so the installation itself is the only thing left to do.
