I got a power outage a couple of hours ago. And now my iMac won't boot. When I power it up, it gets pass the white screen with the apple logo. The screen than turns blue with a spinning cursor. The cursor spins for about 10-15 minutes and stops but the normal login screen never appear and it won't boot into the desktop either. I just got a blue screen.

I have boot into the install Disc1 and did the disk repair and premission repair but it didn't help.

Any idea?

    When you boot from the install disk does it see your hard drive in the system prefs-->Startup Disk?

    Hi Lenn,

    Yes, the Macintosh HD does show up in the Choose Startup Disk window.

    Have you tried resetting the PRAM? Maybe unplugging the powercord from the imac and waiting a few minutes. Then plugging it back in and rebooting.

    Yes. I did that a few times already. No use. I can't boot into safe mode either. Same problem.

    So when you boot from the install disk that works. Sounds like a software problem then. Something might be corrupted. I might try to do a full reinstall of the system.

    I am trying to avoid reinstall but it looks like I don't have a choice.

    Thanks for all your helps.

    Perhaps an Archive and Install so you get a new OS X but can avoid losing all your stuff.

    Yap. That is what I am going to try first.

    Thanks.

    Oh man, what a disaster!

    I tried to do an Archive and Install but the installation hanged at the end of disc 2 after running an iWeb script (according to the install log) with about one minute left. I have waited for two hours but it just hanged there with all the drives spin down.

    To make the problem worse. There was no way to quit the install at that point because all the menu items were disabled. The only way out was to power off. But when I powered it back on, it booted right into install directly asking for the disc 2. If I put the disc in it will install again and hang at the same spot.

    Disc 2 contains iLife. I know Apple wanted to make things simple but why can't they give me an option to skip it? After all, iLife was already installed.

    I finally got it working by booting from disc 1 and did a clean install. It took me all night to re-download all the updates and reinstall many applications. Fortunately, I have my address book, calendar, and most of my works backed up to .Mac so it wasn't a total lost.

    On the bright side. Now my iMac is working better than before. I used to have problem getting auto sleep to work but now it works perfectly. Safari also had problem accessing charts (but Camino was fine) in a few web sites like schwab.com. Now everything works.

    Lenn and David. Thanks for all your helps.

    Now I am looking for a better backup solution so that the recovery won't be this painful if disaster strikes again. Any suggestions?
