Thank you for your response.
None of the key combinations take me to anything useful.
i wind up at a screen with a folder and question mark, circle with a lightning bolt or internet recovery. At no time are any bootable disks or usb drives displayed.
internet recovery doesn’t work because my wi-fi isn’t being discovered.
This has been very frustrating.
Likely the Hard Drive has died, see if you can get someone to install OSX on an external drive for you.
Thank you for your reply.
I have created a bootable usb drive but my Mac doesn’t recognized any external drives.
Are you using a wired USB Keyboard & holding Option key at power up?
Yes, I’m using a wired keyboard and a wired mouse.
When you startup your Mac hold down the ALT/OPTION key to engage the select Startup Disk window.
Thank you for your reply.
All boot key combinations result in one of three screens: folder with question mark, circle with lightning bolt or internet recovery that can’t find my wi-fi network.
