Is this possible? I am working on a "Multipass" as they are called by Hak5. I've made one with several Linux Distro isos, an all versions installer of Win7 / Server 2008 R2 and multiple versions of XP. And since I know you can install OSX from a usb drive, I was wondering if anyone know if it is possible to launch the installer from a grub commandline? Especially if it installed on a separate partition on the usb flash drive?
