I had to stop the installation of an older version of Mac OS X (10.9 to be precise) in Parallels, due to a problem with the OS X installer. I now have that sorted, but need to know if I can resume the installation or if I need to start over. There is an alias of the virtual machine on my desktop, and when I run it, I get a terminal-style window, but with no indication of what I should do. Attaching a screenshot of the window.
