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