In W10 boot camp to OSX volume not found

When i finished installing W10 and boot camp drivers i cant start OSX by using the bootcamp stortcut from the tool bar. This problem appeared after installing winclone 6. The only way to go back to OSX is using the alt key. when i want to start from the boot camp icon i got error: “can not find the OS X-startup volume”.
Anybody a solution?

Do you have High Sierra? If so, this is a known issue about the boot camp drivers not support the new filesystem, AFPS:
