Try Safe Mode. Power down. Power up and hold shift key down until the Apple logo appears.



That's not going to do anything. Safe mode just disables non-critical items (non-Apple kernel extensions, user installed fonts, startup items, etc.). It's used for troubleshooting issues that may occur within OS X. In this case, OS X isn't even starting to begin with.

when you launch into time machine go to disk utility and verify the disk. Likely you will see errors on the disk. Try to repair it, if that doesn't work your hard drive probably has a critical error you need to go to the apple store if it is under warrantee, if not under warrantee fix it yourself, unless you want to spend a little more money and let them fix it.

Also do you have a OS X disk?

I don't necessarily agree with that. It could be all sorts of things. You don't know it isn't booting into OSX, all we know is that he can;t see it. I found this--

He certainly got nothing to lose but about 30 seconds of his time.

I had the same issue with my 2008 iMac and Apple support walked me through the fix yesterday...

1. Shut the computer down by holding the power button for 10 seconds
2. Restart the computer and press shift at the same time until you see the progress bar start moving
3. Once you reach the point where your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password, then hit Enter.
4. After a moment, you should see the spinning beach ball
5. Your screen should then move on to something along the lines of "Completing OSX Installation" (I can't remember the exact wording). Let it finish. After that it should go to your normal desktop and the issue should be fixed. (If your screen goes pitch black during this process, hit the space bar. I thought it wasn't working, but the screen was just sleeping).

Apparently it's an issue with an automatic update that never quite got past the login screen.
