Can't access windows boot camp partition
I installed Windows 10 on my hard drive through boot camp and cannot access Windows on it anymore. I can't select it as the startup disk and can't access it on disk utility. It just lists it as disk0s4 and not even the name. When running repair, it gives me this error: "Unknown filesystem version: 5.3d". How can I fix it or get my data off it?
