    Hi, all,

    I'm trying to get Mountain Lion to install and run on VirtualBox 4.2.4, and followed the instructions I could find. Most of Gogole's referenced page deal with running OS X on Windows, of which I don't care the least.

    However, I keep on getting this, which is not an error, but as I understand, the vanilla Mountain Lion I got doesn't boot.


    What am I not doing properly there?

    Convert .dmg to .cdr

    I have been trying to install Lion into VirtualBox 4.2.6 and ran into the same screen. Converting the installer image from a .dmg to a .cdr (CD/DVD Master) using Disk Utility got me past that and let me get stuck at a different place. But at least it started running the installer before it just hung :(
