When I get to the screen where its says hit any key I can then choose my ML partition or my new Yosemite partition. Here is the issue. My primary partition is ML and it is highlighted. When I switch to Yosemite ML unhighlights and yet Yosemite doesn't get highlight but i know it is selected because when I hit enter it starts booting Yosemite. Is this normal or how can I fix it so that Yosemite gets highlighted when I pick it.' If I stick my unibeast usb drive it and run from that all three can get highlighted "ML, Yosemite or the usb drive itself' So there is an issue with the chimera on my internal drive I think. Can I erase it somehow and reinstall chimera fresh from the newest Multibeast?
