Wow Mark, you're lucky. I normally have to wait about 15 minutes minimum!
before my USB drive boots. Or, are you talking about an installer volume,
not a full fledged OS image. Also, have you really had success hitting the
option key and releasing right after the chime? I'm not in the least bit
doubting you. It's just that I've normally had to keep it held for about
another 10 seconds after the chime finnished. That might be slightly
overkill, but I know it didn't happen instantly if I released when the chime
went away. Would like a little clarification on this, if you don't mind.
Chris.

Hello Brian,
I'm not Chris but, as I understand your dilemma, the problem is that you
have not yet successfully booted into your USB drive.
Normally, I recommend that a blind a low vision person, working alone, use
the Startup disk option located in the System Preferences, to subsequently
boot into the USB drive upon restart. However, it sounds as though you have
already erased the internal drive so this is not an option.
Here's how it works:
You must successfully boot into your USB drive in order to enable VoiceOver
via the key combo Command+F5.
Do the following:
While the Mac is powered off, hold down the Option key and keep it held down
until you hear the startup chime; after which, you may release the Option
key. At this point, you will see a list of all of your bootable devices,
connected to the Mac. If, as you say, your internal drive has been erased
and is therefore not bootable, it will not be listed. Understand that one
cannot use VoiceOver in order to select the drive, using this method. You
may use the arrow keys to highlight any of the items in the list but there
is no VoiceOver feedback. Once you select the drive you want, press the
Enter key. It may take as long as 5 minutes for the computer to boot into
the USB key. Once it does, you can then enable VoiceOver via the key combo
Command+F5.
Mark

Chris,
Just wanted to make sure I have this correct. Start the computer while
holding down the option key, then hit tab and enter? Is there only one thing
I am tabbing to? When do I try and turn VO back on? Thanks,

Don't arrow. That's your problem. You wanna hit the tab key when in the
boot menu. Tab and shift tab. Don't arrow.

Hey all,
So I started my roll back to Yosemite and am stuck. I was able to erase
the El Crapitan from my hard drive but do not seem to get VO running when
I try and boot up with my bootable USB Install Yosemite drive. Everything
I have read says you have to restart your computer and hold the option
screen to get to the screen with your bootable thumb drive on it. For some
reason I am thinking this screen might not work with VO as I waited over
an hour and could not get VO to turn on. Does anyone happen to know how to
arrow without VO running to get your bootable disc to launch? If not, is
there anyway to boot in to your drive using disk utility as I am back in
disc utility but do not see anywhere I can do this and selecting reinstall
OS and hitting continue just gives me a you are not connected to the
internet error message. Thanks for any help.
