Has anyone been able to install or even get past grub on the installer for x64 Ubuntu 12.04 or mint 13 in parallels on their rMBP? If you own one could you please try? Mine kernel panics for both those installers right after selecting the install option on the initial boot from the iso. I submitted a detailed support ticket with debug logs to parallels almost a week ago and the response I got back was "Ubuntu 12.04 is beta support." So I'm stuck running in virtual box for now. Both those os's run fine on a 2011mbp and MBA under parallels. Thanks!
