• Virtualbox: This virtualization suite is free, and though it doesn't offer official support for Mac OS X, it works well enough.; Mountain Lion bootable DVD: Unfortunately, the standard method for installing OS X Mountain Lion on PCs (which uses a paid copy of the Mountain Lion installer) doesn't work with Virtualbox.
• Start VirtualBox. Create a new VM with a hard drive, guest OS Mac OS X 10.7 Lion (64-bit). Remember the name you give to the VM and do not start it after creation. Go to VM Settings, in System change chipset to PIIX3. In Display change video memory to 128MB. Click OK to save settings. Exit VirtualBox.
• An unexpected and pleasant surprise. For me, Mountain Lion OS X 10.8.2 (build 12C60) runs as a guest with VirtualBox 4.2.4 r81684 on a 12C60 host, MacBookPro5,2 with 8 GB memory: with EFI with fewer of the OSx86-oriented additions that I found necessary with some previous releases of VirtualBox.

1. Start VirtualBox.
2. Start the newly created VM.
3. VirtualBox will offer you the option to select a CD image file. Use InstallESD.dmg.
4. It should now boot into the OS X install and give you a menu with options (after selecting your preferred language). Start Disk Utility.
5. Partition the VBOX hard drive as 1 partition, MacOS Extended (journaled).
6. Exit Disk Utility.
7. Start OS X install, proceed as normal.
