Mac OS X
Q: How do I get my computer to recognize this boot disk?
Hello,
I followed the instructions on how to create a bootable installer for OS X El Capitan. I set it up on a USB drive.
But how do I get my computer to recognize it as a bootable drive? If I go into System Preferences under Startup Disk, it is not listed there. If I restart the machine holding down the Option key, it doesn't give me an option to boot from this USB drive.
What do I need to do to get my machine to recognize it as a bootable drive?
The reason I'm trying to do this is so I can unmount the hard drive and run Disk Utilities. Is there an easier way to do that?
Thank you,
Bruce Fairbanks
