Startup Manager shows no devices but internet recovery
After selecting the ALT?/OPTION key there are no devices to be selected, just Internet Recovery.
I installed the OS from a recovery (cmd+alt+R) erase the disk, formatted it then I did a clean install High sierra on a MacbookPro 17" 2011.
it started fine with no issues after the installation when I performed an OS update from the appstore the laptop cannot find the OS anymore and I get the "Blinking Folder" ... what can I do?, if the startup manager does't show my SSD?
MacBook Pro 17", macOS 10.13
