Help! Missing Macintosh HD as startup disk

[Int2grate]

Hello

I believe that my copy of Windows in Bootcamp automatically upgraded itself from Windows 7 to Windows 10. Now, when I boot and press the "option" key, I no longer see the "Macintosh HD" as a choice. If I run "disk utility" from the recovery partition, I see the "Macintosh HD" partition. When I run "first aid" on it, no errors are reported.

Desperately need help...

Thank you
Steven

You could select 'Reinstall macOS' in the recovery partition and point it to Macintosh HD. This will not wipe any of your data/applications and it will just reinstall the OS components.

One of the reasons I would not use BootCamp.
Instead, run Windows inside a "virtual machine", which will work in most cases.

I would use BootCamp ONLY if the VM solution didn't work for my needs...
