    My mother-in-laws Power PC Mac Mini stopped working the other day.
    After booting to disk utility and seeing that there wasn't a hard drive mounting I assumed the hard drive was dead.

    I ordered a replacement from OWC, opened the mini, and put in the new hard drive. Now I can't get the mini to boot from CD all I get is a blank gray screen and eventually the folder with a question mark icon.

    Any idea?? I was under the assumption I could boot to disc again, format and reinstall on the new hard drive. I also can't get the CD to eject but it is spinning up .

    Any ideas??

    Maybe it's not the hard drive that's broken...? Could you test the one you removed somewhere else?

    Boot holding the C on the keyboard, if that does not work boot holding the option button and select the CD.

    Yes, the drive is dead....I put it in a external enclosure and Disk Utility did not recognize it nor did it spin up.

    Neither of these work.....for some reason it doesnt want to boot from the CD. I can here it spinning up but it always tries to boot from the blank hard drive.

    I think I may slap the new drive in the external enclosure and try to install OS X on it from a different mac

    You can try to hold option down when booting.

    You can try putting the drive in an external case. If that doesn't work disconnect drive, boot from CD . Then connect the external drive.
