    I am looking to install OS X on my old macbook pro hard drive that is in a usb hard drive converter case.

    History - A while back I personally replaced my hard drive because my old one had a corrupt install on and I

    wanted to upgrade, but there is now an unrelated problem with my Mac Book's logic board that is apparently

    covered by apple whether it is in or out of warranty because of a defect in the GPU (Black screen of death issue! ) As my mac was out of warranty I didn't think twice when I

    recently upgraded my hard drive myself, now I am a little anxious as I believe Apple will use this to void their

    promise to replace the logic board in OR out of warranty beacuse I replaced the drive myself.

    For this reason I think it is best that I restore the corrupt hard drive and then replace it in the mac before I

    return it to Apple, is this the right thing to do?

    The logistics of doing this are a little complicated as I don't have a screen (or the option to use extertnal

    screen) on the macbook due to the gpu issue so cannot simply put the hard drive back in and reinstall while in the mac.

    I am looking at the option to format my old drive and then install osx on it in the external caddy case. Is this sensible/easy to do?

    I cannot afford a new laptop or to pay for the repair so I am desparately trying to get it fixed by apple.

    Any advice on either issue would be amazing!!

    Have you got another Mac?

    If so, you can fit the old drive and install OS X using target disk mode.

    I have a g5 not sure if the hard drive will fit into that?

    I meant fit the hard drive in the MBP and connect in target disk mode but I don't think you can install to an Intel Mac from a G5.

    It wont work if you were planning to install OS X to the USB drive using the G5 either.

    I have a similar Situation.
    A friend wants me to install SL on her MacBook Pro, but her disk drive is apparently broken/malfunctioning.
    I booted her computer in target disk mode, and tried to install osx in her drive from my own MacBook Pro's optical disk drive.
    However, every time the installation starts, about 15 minutes into it, my computer seems to restart, and goes to the apple screen. I waited and waited, but nothing happened.
    I tried it again, an my computer would still spontaneously go to the apple screen.
    What's going on here?
