fazintosh posted a question in OS X Mavericks 10.9Hi there I have just installed Yosemite Zone in the same HDD of an existing Win8 Of course I have created a dedicated partition for OSX according the howto procedure and all looks going well, until the final reboot. The thing is that yosemite zone does not install automatically the Clover tool, for multi boot. 1st prob = without the use of the usb stick I am not able to select the OS. It shows boot0ss: error 2nd prob = It is now impossible to launch Win 8. It is booting then after a couple of sec "shows error on starting" Now I have a useless PC :'( Please hellp Thanks to all for precious tips Faz'
