I did it!!! I'm back up and running (and faster than before)
Hard Drive failure made the iMac inoperable. I remembered a Coworker's laptop with your sticker. I thought maybe I can do that too.
It went great! I haven't repaired my personal electronics before. But I did it.
I watched the video to get an idea of the work involved and felt optimistic That I could do it. When the kit arrived an rewatched the video and then followed the step by step guide. Very little issues, except the user trying to skip steps. OK i was excited that I was doing it. There you have it.
When I plugged it and started it up it worked!!! I could see the expected the boot screen, that felt good.
Follow the instructions as the site guides you. It worked great.
