I'm trying to install OS X 10.8 Mountain lion on my Macbook Air 1.1 (Early 2008) with MacPostFactor. Everything seems to go well. MacPostFactor says its finished, and tells me to click to restart. I click and my Macbook doesn't restart. When I restart manually, and hold alt to select the correct partition to boot from, I can see the partition MacPostFactor installed 10.8 to, but when I click on it, it doesn't boot and just boots into my 10.7 Partition. Anyone have any ideas? Thanks in advance.
