    New HD installed in iBook, but cant boot off it

    A colleague replaced the hard disk in her iBooks over the holidays, I gave her instructions and said to her to bring it up to me (i had taken an image of her old disk)

    Started it up, wouldnt recognise the disk, no massive surprise, so I put in an OSX install CD, went into disk utility and partitioned it (it was recognised fine)

    Restarted in target mode and put the image back onto it no problems.

    But now it still wont boot, it just comes up with the folder and question mark.
    Ive gone back into disk utility, its still detected, formatted as mac os extended (journaled) and the partition map scheme is Apple Partition Map, which is right isnt it?

    What do I need to do to get it to boot? Even if I start with option held down, it wont come up as a bootable disk.
    Do I need a firmware upgrade or something? Its an iBook G4, and its a 160GB HD thats been put into it.
    I did check before she ordered the disk, and it did seem that other people had upgraded to that size with no problems

    Is it actually formatted as a bootable partition? Is the bootloader properly set up? (I'm assuming that OSX is akin to other forms of Linux in using a bootloader)

    Have you tried doing a normal OS X install from the boot media? (I am assuming not as you mention imaging).

    OS X uses EFI, which I assume needs installing via a full install routine.

    No need to reinstall just set the copied partition to active using the fdisk tool on the OSX DVD:

    What did you use to image the drive and then re-image it back?

    I think it may have something to do with the spin up time on the disk. We replaced a drive in an imac here and one disk installed fine with netinstall, it just wouldn't boot. Another make of drive (same size) shows the question mark for a second or two then boots as normal.

    As a secondary thought, does the laptop have the latest firmware on it. Perhaps it is not handling the larger drives different specs, like the spinup time as gracefully as it could.

    Well I installed OS X, then imaged it again and it is now booting fine
    Doesnt look like the spinup time was the issue in this case

    The partition/System folder may have needed to be blessed?
