Just download the Lion Diskmaker app, unzip it, and run it. You'll basically need to click four buttons: "10.8 Mountain Lion," "Use this copy," "Create a boot disk," and, if you're using a USB flash drive as recommended, "An 8 GB USB thumb drive." It's really that simple; Lion Diskmaker takes care of the rest. The process will take about 30 minutes or so using USB 2.0 (it should be faster if you have a USB 3.0-compatible flash drive and newer Mac).
The Extensible Firmware Interface (EFI) partition contains the boot software, the Macintosh HD partition contains the Mac OS X 10.8 Mountain Lion, and the Recovery HD partition contains the Mac OS X Lion Recovery.

The Mountain Lion OS also improved the user interface of the MacBook interface.
I go to File --> New, click "Install from disc or image," select the corresponding InstallMacOSX.dmg disk image file, selecting the specific OS version (I tried selecting the 32-bit and 64-bit versions in separate attempts since I'm not sure which the linked installer is) and both times when the instance reboots, it says it couldn't find a hard drive or CD-ROM drive ("No compatible bootloader found" for each one). VMware then opens a window saying "No operating system was found." I get the same error when trying Mac OS X 10.8 Mountain Lion, and I haven't yet tried other OS versions.
