Hello fellow Mac users.
I have an iMac (Core i5 3.1 27-Inch, Mid-2011), running Mavericks which would no longer boot past a grey screen. After disconnecting all peripherals, zapping p-ram and attempting to boot, no change. However, there was an unusual clicking noise which led me to think that hard drive was the problem. After scraping the change from my sofa, I purchased the WD 4TB Black hard drive and installed it. 2 years ago, I replaced the hard drive on my 2008 iMac and it has been working like a charm ever since. No issues.
I tested the old drive by inserting into an external drive enclosure and connecting it to my 2008 iMac. The drive clicked and snapped continuously and was never accessible.
After the new drive was installed I attempted to boot from the original system disc (ctrl-c), but there was nothing but a grey screen again.
When I attempted to boot from ctrl, I did see the prompt to boot from CD.

When I clicked on the CD, the Apple logo was displayed.... and remained with no result.

At first I questioned whether I properly seated the cable zif connector when I opened the machine but I don't think I would see a display at all if this was the case.
I could hear the CD turning but I just can't seem to understand why I can't boot from the CD to the new hard drive.
Is there something that I am missing here?
Any feedback would be appreciated.
Thank you.
