my iMac is having problems booting up. It'll make the start up sound, white screen apple logo...then a progress bar(never seen that before; use to seeing the circle) appears does about 20%? then the iMac shuts itself down.
I can still boot up into windows through bootcamp perfectly fine.
I've followed these steps to try resolve my problem up to 6.1.

I encountered a problem when it was repairing the disk when i booted it from DVD and went to disk utilities. Didn't say what the problem was though.
So i decided to reinstalled the OS and that apparently encountered a problem as well on the HDD. But when i restarted it after that(the attempt to reinstall the OS) and just started the iMac up normally without going into safe mode or booting from disc etc, it works! So i thought ok cool its fixed but to be safe ill just back everything up and restart it. And it just goes back to what it was doing before, getting to about 20% on the progress bar at the boot up and shutting down.
But if i select to boot from the DVD choose the language(as if i were going to reinstall the OS) then restart the iMac after the language has been selected it works fine. I can log in and do everything i want.
I tried that again and it works. I put my USB backup HDD in, jump into time machine take it back to start of july but still get the boot up problem. I realise I've kind of answered my own question, but going through to boot up with DVD then restarting it is starting to frustrate me. I'm bit reluctant to format the HDD at the moment till i can really pinpoint whats wrong with it.
Could it be a bad sector in the boot up? Part of the HDD has corrupted? Sorry if there has been a similar problem on these forums, but I'm just stressing out over this and may have overlooked some other possible solutions.
