I created a Yosemite boot USB, from the App Store version 10.10.1.
When I hold
option during Boot, the USB drive doesn't show up on the menu.
I have an aluminium MBP, bought in 2009. It is the full body aluminium with the Superdrive.
Per Apple, this is my machine:
MacBook Pro (13-inch, Mid 2009)
The only drives I see when holding down
option are Macintosh HD and Recovery. When I try to run recovery, it runs for a little and then goes to a "no" symbol, with the spinner still spinning. I am concerned that the HD may be dead/dying, but I don't want to jump to that conclusion yet.
How do I either boot to my USB, or just get a restore done?
I have already successfully backed up my files. I just want to restore the machine.
I made the USB Boot drive from this guide:
Specifically choice number 1, where I downloaded the OS from the App Store and ran the terminal commands on a pre-formatted USB drive.
Below you will see the Disk Utility for the USB drive. Not sure how to tell if it is a Boot disk or not.
The below screenshot shows EFI in Debug mode in Disk Utility.
For what it's worth, when I plug in this drive into my working MBP, I see the "Install OS X Yosemite" get mounted in Finder.
Here is a screenshot of the "Startup Disk" option within "System Preferences" on my working MBP that has the Bootable USB plugged in - which proves that it was properly created, I believe. You can check the screenshot to confirm though.
