Hi All--

(Tried to attach photos or embed them with HTML but that didn't work. I know It's a pain to have to click the link to the photos, but I'm posting those links until I can figure out how to get them viewable within the message. When I do, I'll come back and edit to make it easier to read this. Sorry about that!)

I hope this is the right sub-forum for this (wasn't sure if it goes here or on an OS section) I had a dead HD in my mid-2012 MBP. I took a working drive (Same size and speed and other specs) from a 2009 MBP with a dead keyboard.

Via cmd-option-r I was able to call up Disk Utility and erase and reinstall the OS.

But I keep getting back to this screen and (seemingly) to have to start the whole process over. I try booting the MBP. Shouldn't it just take me right into the Finder?

What am I missing? I've put a new Hybrid SSD in a MBP 2015 and installed the operating system on it with no problem, but it's been a while, and most of my experience was back when we installed the OS via CD's or DVD's.

by the way, here's the partition info:

And here are the stats when I've run first aid:

Lastly, one thing I don't get is when I pull the specs on the system drive. it says it's not "bootable." I don't get this. Is the fact that it's not bootable related to the problem I'm having?

Is this a 13" MBP? If yes, the machine's sata hard disc cable could be bad.

If the 2009 MBP is also a 13", you could try putting its sata hard drive cable into the 2012.
 
OP:
BEFORE YOU DO ANYTHING ELSE...

Do you have a brick-n-mortar Apple Store reasonably close by?

If so, take the 2012 MacBook Pro there, and ask them to check the internal drive ribbon cable. These are notorious for failures on the MBPro that you have. When the cable "goes bad", it will look as if the -drive- has gone bad.

An unsuspecting user will replace the drive (again, thinking the drive had failed), and the new drive will not help, because the CABLE is bad.

I believe Apple is replacing the defective cable FREE OF CHARGE (not sure if this replacement program is still in effect).

Do this first.
Then get back to us.

The cable is also replaceable yourself -- just as easy as changing out the drive.
You can get a new one from ifixit.com, or other sources.
You can find the part number at ifixit.com.
