Should i update my mac. You mentioned troubleshooting, did it include these:
Thus, find the name of the disk volume in question, then look under the 'IDENTIFIER' section to find the disk ID, it will appear on the right side of the terminal report: As that command will print out all volumes and their disk identifiers, it can provide unnecessary information. Power up (or restart) your Mac. Press down on the Option key while the Mac boots. After a few moments, your Mac should display the Startup Manager, which will show you the available boot. Click the Startup Disk icon in System Preferences, or choose View Startup Disk. Select your startup disk from the list of available volumes. The next time you start up or restart your computer, your Mac starts up using the operating system on the selected volume. Temporarily change your startup disk with Startup Manager. To cut a long story short, the Startup disk is showing as missing. I tried all the trouble shooting and seem to be unable to identify and fix the problem. I was able to download the OS X on my external hard drive so I can operate the Mac now. But the problem has not been solved. What do I do from here to repair the disk.
