-
Nov 8, 2013 12:30 PM in response to macjackby seb29,command R freezes the computer so starting in recovery is not an option. I ran Disk utility from the Utilities screen but it said the partition map appears to be ok. Any ideas?

Nov 8, 2013 12:35 PM in response to seb29by macjack,What does "New CPU" mean in your specs, did you have the CPU replaced recently?
What happens when you boot up holding the option key into Startup Manager.
Do you the the Recovery Volume and can you choose to boot from it. Navigate with your arrow keys the mouse will be non-functional.

Nov 8, 2013 12:44 PM in response to macjackby seb29,Tried that but it just brings me in the same loop again... Utilities screen, then "error occurred while adding a recovery system to the destination disk".
Any ideas?
CPU just means it's a work computer here.

Nov 8, 2013 2:45 PM in response to seb29by macjack,If you can't start in Recovery Mode and your Mac shipped with 10.6 or later, make an appointment at the Genius Bar.
If it shipped with 10.6 or earlier startup holding the "d" key from Disk 1, you should be able to use DIsk Utility there.
But I'd erase the disk and start over. Do you you have a good backup in any case?

Nov 8, 2013 5:00 PM in response to macjackby seb29,It shipped with 10.8 but I would prefer not lugging the entire iMac into a crowded mall if at all possible.
1) What if I load Mavericks onto a USB and try to boot it from there?
2) If I erase the drive, what would my steps be after that point?
Thanks!!!

Nov 8, 2013 5:15 PM in response to seb29by Drew Reece,You can boot from a USB installer, you can create that via http://diskmakerx.com or use the standard Disk Utility instructions (put simply - restore the InstallESD.dmg to the USB stick).
You can then use the regular installer utilities (Disk Utility etc) to inspect your disk or try repairs. It does sound like starting over will help.
To erase & install…
Open Disk Utility, select the internal HD, select the Partition Tab, create a new single partition & select GUID Partition table in the options, Apply that & all the data on disk will be gone.
You can then Quit Disk Utility & continue to install OS X. The installer should re-create the recovery partition for you.
Don't forget you can choose to migrate your backed up data via the installer or you can use /Applications/Utilities/Migration Assistant at any point in the future (e.g. once you are sure it boots OK).

Nov 11, 2013 7:03 AM in response to seb29by keg55,Have you tried Internet Recovery? It's not the same as "recovery mode" or booting to the Recovery HD.
Press/hold the COMMAND+R+OPTION keys until you see a spinning globe to boot into Apple's servers and their Recovery HD. From their OS X Utilities menu you can use Disk Utility and Reinstal OS X that came preinstalled (10.8 in your case) on your Mac.

Nov 11, 2013 8:06 AM in response to keg55by seb29,I tried this option but it starts then gives me an error screen of a world with an exclamation mark followed by "Apple.com/support. -2003F"
Any ideas?

Nov 11, 2013 8:24 AM in response to seb29by keg55,Boy, no idea what that is. I haven't experienced that error before with a Mac using Internet Recovery.
And you tried the 3 keys I mentioned, right? Not just 2 (Command+R), correct?

Nov 11, 2013 8:34 AM in response to seb29by seb29,Yes I pressed all three keys.
Now I'm in Disk Utility under First Aid trying to Repair Disk but it keeps saying
"Invalid B-tree node size
The volume could not be verified completely"
Any ideas?

Nov 11, 2013 9:15 AM in response to seb29by Eric Root,You posted earlier you had a backup, so at this point I think your only option is to erase the disk using Disk Utility, and hope the reformatting will clear up the 'Invalid B-tree node size'. Mac OS Extended (Journaled) is the normal format. After that, try booting from the USB and reinstall 10.9. Use Setup Assistant to restore from your backup.

It honestly sounds to me like you have a hardware issue. Specifically, your hard drive. Are you able to install to an enternal drive like a USB drive after going into Internet Recovery?
