    Are you sure that OSX is still installed?

    If so: start in Windows, in the Configuration Pannel, there is an applet called StartupDisk, set the OSX disk. Then restart.

    Thx Lex,

     

    As it happens, I reviewed multiple articles. Seems upgrading windows needs a upgraded Boot Camp (which I did not install). Short story, downloaded the latest boot camp (5.1 i think). it installs in windows thank god and got the Boot Camp back in the windows tray. All ok now. Thanks for your help. Cheers.

    You did OK ( but for the points: you can not give yourself points, but don't worry about that).

    When you upgrade to windows 10, it may or may not ask for bootcamp6: this is not a higher version of BootcampAssistant, but it is a set of newer drivers and they install in Windows itself. When bootcamp 6 is not asked for, the drivers are already ok.

    Have fun,

    Lex
