iMac stuck on grey logo screen

[Drustin]

My iMac won't boot up and is stuck on the loading screen with the apple logo. Ive tried almost everything. It started doing this after I had to do an archive install (of OS X) because it was taking 20minutes to boot up. I have windows on a separate partition and that boots up fine. Ive been having a lot of problems recently with my iMac and its getting annoying....

Sounds like you may have a bad harddrive. Still have a warranty on it? I would hit them up for a repair.

Does OS X start up successfully in safe mode (startup holding shift)?

I'll 2nd that. Definitely sounds like a bad/dying HHD.
