Thank you so much.
When I tried that, I get to a window asking me to choose Startup Disk to select to restart. But when I click the "choose startup disk" I get the the same issue with no options to select to complete the request.
Also, I was willing to try to erase, but the erase button is not activated for me under the Disk Utility to even select that as an option.
I tried to do a chat with Apple, but after putting in the serial number of my laptop, I got a notice that my machine isn't eligible for chat support.
I am trying all this because when I start my laptop I get a blinking folder with a question mark on the startup screen.
