    MacBook Pro A1150/OSX 10.6

    OSX fails to boot. Stuck on Apple logo with spinning wheel. Tried safe boot and resetting PRAM. No luck. Tried to get to the Disk Utility via the install disk but fails to boot from CD. Internal optical drive is dead and am trying to boot from an external USB connected optical drive via the C key at boot up option. Removed the HDD and verified it on my desktop G5. It passed and is OK. Don't know what else to try or what the problem can be. I can only think it may be system board related.

    ¿? :confused: ¿?

    try holding down the option key with the external optical drive connected to see if it's even detected. If that doesn't work, the next thing to try it to get a bootable image of the OS onto a USB key and try to get into disk utility that way.

    Thanks for the kind reply. With the option key pressed I was able to view the HDD AND the external optical drive. Tried the HDD first and had the same error as reported; can't get pass the Apple logo+running spinning wheel. Booted up again with the option key and chose the external optical drive. Was able to run the disk utility and verify the HDD (no problems) and permissions (some errors were found and repaired). Situation remains the same, can't boot pass the logo either normally, from the installation disk or safe boot.

    OSX installed is 10.4.11 and the installation disc I used to access the disk utility is 10.5

    Unfortunately, this does happen where you repair disk and permissions and it still doesn't boot up. The next step would try to get into safe mode but you've already tried it. Your only option is to back up your data from the HDD and do a reinstall of the OS.

    Thanks for confirming what I suspected would be my last option. Fortunately I can access my MacBook HDD on my G5 and make a backup. Out of curiosity, is this a scenario that Disk Warrior would have been able to resolve ? TIA

    It could and it's definitely worth a try if you still want to continue diagnosing the issue vs. just starting over (it will depend how much you need to restore, if you have a lot, you probably would like to exhaust all options.) but what I find more often than not is that these types of software don't fix the issue.

    Resolved

    Re-installing fixed whatever the problem was. Thanks iLog.Genius for your kind replies.
