    At step 3, how much boots do you mean? When I keep holding the keys, it cycles..

    only 2 in total - you should hear the chime twice.

    After successfully booting up my MacBook 2,1 from USB and installing, I was unable to boot up on my internal hard drive (started the process. Got past grub screen, then was grey/black screen and hung up). I used the PRAM reset and now when I press the power button I hear the laptop try to turn on but it doesn't have a chime and only stays a black screen with the front power light on. I can't even hold option to get to the startup disk screen. Any ideas how to fix that?

    Hey David,

    Better to open a separate thread to troubleshoot your specific situation.

    Start by seeing if you can still boot successfully from USB, as well as what happens if you use the option-boot and manually select the internal HDD.

    I did try booting with the USB drive by holding option + D and just with it in. No luck. As soon as I hit the power button it makes a noise like it tries to start, but there is no chime and the screen remains black.

    David and Rory -

    It is better if you open separate threads if you have an issue with your machine. These articles are meant to be as general as possible, and the comment should really pertain to the article and not anyone's specific situation.

    We'll be happy to help if you open a new thread and describe your issue in detail, including what you've tried so far to fix it.

    Forest,

    After your initial suggestion, I did create a new thread specific to this issue (link below). https://neverware.zendesk.com/hc/en-us/community/posts/115000522707-Macbook-2-1-will-not-boot-after-PRAM-refresh
