So I'm trying to restore Mavericks on an iMAC.
Internet Recovery loads fine but "Install OSX" shows no disk to select, so I run "Disk Utility".
It shows me "Untitled" drive which is a 3TB HDD (and the startup disk of course). It is "Online" and "Repair" says it's working fine. I select it but all options and buttons are disabled. I can't do anything.
I can't attach any screenshot because I'm in the middle of Internet Recovery.
