Mavericks Install Failed?

This has happened every time. At this point I am wasting my time. I don't have a time machine back up, however we are defintely getting one now after this crap happened.

Going to Apple today at 3:30 to see what they have to say. This is not a coincidence that it happened to so many people. Something happened with Mavericks.

FWIW.. My iMac did the exact same thing... so I unplugged all my external drives.. I hit continue and selected Disk Utility and saw my MAC OS hard drive was grayed out.. so I went back to the previous Install screen, and hit the little back arrow which took me to the Language selection screen, then I hit Continue and it some how upgraded successfully...?!?!

I'm up and running on Mavericks now..

Not neccessarily a fix, but more of a temporary solution for people who are worried about loosing stuff that they had not previously backed up.

You can plug in an external drive and reboot in Recovery mode (command+R). Once up and you've selected recovery, you can choose to redownload Mountain Lion. Do this and download it to the external drive. You will have to go through a number of prompted steps and it may take up to an hour or two, but eventually you will be able to boot your computer off of the external drive with Mountain Lion.

Once you're up on your 'new' Mountain Lion desktop, open the finder and you should be able to access your internal drive (probably labeled 'Macintosh HD'). You should be able to view and browse all of your documents and if you'd like, you can plug in a second external drive and manually drag-and-drop the files you are concerned about. Hope this makes sense. If not, I'd be happy to elaborate further, but it worked for me and I was able to save a number of photos, videos, music, etc. that I had not backed up yet.

Finally restore from time machine. I will hold on the upgrade and wait for few days to see any solution for this.

You can't repair the disk while you are booted from it, reboot to Recovery, use Disk Utilities (from Recovery) to repair the startup disk.

Command-R boots to Recovery, hold it down as soon as you hear the chime.

This worked for me. Thank you!

You're welcome.

Thanks - finally got out of the loop and am now restoring. Waiting time is listed at 6.5 hours. I will NOT try to upgrade again until a fix is provided. Glad I didn't attempt to install on my wife's MacBook Pro!

I am having the same problem.

When I do cmd R it asks to choose a network, presumably my wifi. All I want to do is repair disk???

Any help appreciated.

I finally updated successfully!

How?

There may be hope for those still having problems. I have been "caught in the loop" all afternoon and into the evening. Then, about ten minutes ago, I started AGAIN and it went straight to the installer without doing ANYTHING. It's about a third of the way through, much further than when I got the damaged disk message in the first place. Maybe not much "help" but thought I'd pass it along. I'll post if it completes.

Took the MacBook Air to apple. Did some diagnostics, found code in the boot up log. Said hard drive crashed. Replacing hard drive under warranty.

I asked if it had anything to do with mavericks. He said no. Lll

I tried to restore from time machine backup, it got stuck trying to find a disk . . . seems the disk has a problem now.

you may need to boot to recovery mode and direct plug the time machine hardisk to the machine.

I don't think the harddisk really damage. As you see so many case happen in here, it is not possible so many case harddisk cash at the same time during the Mavericks upgrade.
