I have a 2011 customac mini, i have a gigabyte GA-h67n-usb3-b3 motherboard. The problem is this, my internet card wasn't working anymore my computer wasn't seeing the car anymore, so I took apart the pc and fixed the problem. Now here's the issue, i've had this happen before, where it just hangs on the apple logo screen, so i normally just restart the computer and let it boot it up, i tried that, but now this time every time i restart it, this loading bar comes underneith the logo for about half a min or so and then it dissapears, and lion doesn't load. I've tried -x, -v, and -v came up saying "waiting for root device" and stopped there. So something is wrong, but it can't be anything serious, i never installed or uni-stalled anything.
ok, i may have found the issue, have no idea why it would be doing this since I again never installed anything, literally just took apart the computer and unplugged and re-plugged certain cords. But anyways when I try and boot CMD -V it ended saying that it was trying to rebuild catalog b-tree, and then it says it cannot repair, then it comes up saying system has been modified and shows like 6 lines of the same thing saying it's a bug. So I booted into disk utility with Unibeast and tried repairing, same thing happens tryies to rebuild catalog b-tree and then it says it fails and cannot repair lion disk.
