I have a late 2015 5k imac with el capitan all ready installed and a 1 tb fusion drive.I installed windows 10 via bootcamp 6 but my osx partition is not visible in windows.I lave googled the problem over the last couple of days and it might have something to do with the corestorage file system.It has been really nice to have the 2 os's co-existing on my previous now dead imac being able to transfer files between the two.Does anyone have the same problem or know of a solution?Thanks
