Will OS recovery overwrite hard drive?
My Mac Book Pro (13" 2014) wouldn't boot past the gray apple (even in safe mode). I am looking at doing an operating system recovery from the Cmd-R boot option. From Disk Utility in (recovery mode) I see a small Base System and a 500 HD. The recovery only lets me choose the HD. My question is: will recovering onto the HD overwrite the data on the HD? I had expected to see two partitions on the HD, one for the operating system and one for the data but I just see the HD by itself. I wouldn't want to wipe out my data in the process. (I am out of the country and do not have access to a lot of resources for backups.)
Is this a good question?
