I believe I had this "can't boot into OS X" situation happen to me and I followed the directions and did not nuke any partition nor did I select the wrong partition. It was pretty creepy -- I tried to boot back into Mac OS X and after the grey screen with the Apple logo, it went to a dark blue screen with the the spinning control and just sat there spinning. I forced a restart after awhile, booted verbose at first and it still seemed to get stuck during the Mac OS X boot process. Then I forced another restart and booted single user. I could see all of my files which was a relief although I did have a backup on our Retrospect server. I did an fsck which found no errors. I issued a reboot command and this time it booted normally.
In the video he uses a third party wireless card. Are other cards, such as the built-in card, similarly vulnerable?
