Need help. I have successfully created a USB for mountain lion os 10.8.4.
But when I boot from the usb using the boot flag -v -x I come and hault at Ethernet Address :00:11:22:33:44
Along with the other error screen. To make it more clear please have a look at the screenshot.
My system details

I would appreciate if someone can help me install ML on my laptop. I have already have a working os 10.7.3 on it.
