Macbook Pro no longer starting after failed upgrade to 10.6
Hi,
My wife was trying to upgrade our 2009 Macbook Pro from 10.5 to 10.6, and the installation failed in the middle. She tried to restart the computer and now the grey screen appears with the apple, then the progress indicator comes on and spins, and then after a minute or two the computer shuts down. Every time.
I tried clearing the NVRAM by holding COMMAND + OPTION + P + R at startup. I hear the computer start and then re-start, so I think the NVRAM was cleaed, but it doesn't seem to have changed anything.
I put in an OS X Leopard upgrade disk, and held the "C" key at startp to open the Disk Utility. I tried to verify the hard disk but got an "invalid node structure" error. The Disk Utility would not allow me to click on "Repair Disk." I tried verifying the disk a few more times just for fun, and got invalid node structure each time except once, when I got "invalid key length."
Next I tried re-starting in Verbose mode. This time it got to a certain point in the start-up process and then just stopped. It didn't shut down, but hasn't moved any farther for 20 or 30 minutes or so. The following image shows what is on the screen now.
Any help would be greatly appreciated! Thanks!
