Hi, I’ve been trying to create a shared partition for sharing data between Windows 10 and OSX El Capitan, but nothing seems to work. I have a 400Gb for OSX and 100Gb for windows(BootCamp), I’ve reduced the OSX partition by 100Gb to create a new one formatted with ExFat (I've found that Exfat is supported by both OSs), but when I’ve tried to boot on Windows it stops on a blue page telling me that my PC need to be repaired using an installation media. When I’ve plugged in the installation media (USB) it told me that there is any windows partition or any previous windows installation in my hard drive. When I returned to OSX, I’ve deleted the BootCamp partition, created a shared partition in Exfat format, and used BootCamp to create a windows partition and to install Windows 10, but once in the installation process, the BootCamp partition is not recognized and it tells me that windows could not be installed in that partition??? Please help, I’m running out of ideas. "Sorry for my English, it's not my native language"
