My son, an ER doc and thus with little spare time, is trying to install OS 10.6 on his imac which has a dead optical disk reader (Apple wanted $500 to replace). So the install is done from an external hdd but this is second try; first one hung at 20% and when he aborted he got ?? on screen. Second try got to '2 minutes to go' and has hung there all night. What should he do?

iMac (20-inch Late 2006), iOS 5

    Has he/you run Disk Utility>Repair Disk on the drive trying to install to? Not Repair Permissions?

    No although I suggested it. But problem is that if he aborts the install process he gets a ?? on the screen indicating, I think, that it is not recognizing his internal HDD. If disk utility is on the new OS 10.6 he bought from Apple, how can he access it without going through the install procedure. Would booting with option helddown  help?

    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.

    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)

    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.

    3. Click the First Aid tab.

    4. Select your Mac OS X volume.

    5. Click Repair. Disk Utility checks and repairs the disk."

    This is what my son wrote: Did this with Apple on the phone. The repair process hung after one hour and then things were worse: couldn't even get this bood done again after!


    Previously he wrote:  Spent about an hour on phone with apple. Tried reinstalling 10.5 Nothing but folder with question mark. Did get to DU and tried to repair the HD but it hung and never made any progress.


    This situation is bizarre! Surely there must be some answer. He is panicked that he may lose everything that was on the HD even though he had Time Machine running.

    Well, I'm afraid he'll have to have it looked at, seems some hard to find Hardware issue.
