In Parallels Desktop 8 (most current version) I have set up a virtual machine of Mavericks successfully. Then I have attempted to update to the public beta of Yosemite. It downloads and seems to install. Then, when it must reboot to complete I can only get this screen and can't get Yosemite to load:
It will then only allow me to select Recovery HD and then it wants to reinstall Mavericks if I select Recovery HD.
I'm looking for recommendations on how I should resolve this, or if it's even possible to run a VM of Yosemite in Parallels 8. Thanks.
