cannot find my HD
Hello,
I'm trying to erase my MacBook and start it up fresh. I might have erased a bit too much... I do not seem to find my Macintosh HD when trying to set up the iOS. Is there anything I can do?
It gives me the option to install mac OS High Sierra.
But when it asks me to select the disk where to install the Mac OS the only option is my external time machine drive which is connected to the computer.
I cannot choose the drive because it says it is locked.
If I start the computer without the external drive connected there is a folder with a question mark blinking... and the suggestion to contact support.aplle.com/mac/startup
