I have a MacBook Air that When it starts up it just shows mant terminal codes and says OS not found. When I enter disc utility the SSD is shown and no fault is present When doing first aid routine but still cant find disc to use it for start up. Have tried erasing everything and installing OS again without any improvements. The main issue is that the Mac cant find any bootable data to start up from but i cant find out why.
Hi,
If your MacBook Air has Intel Processor, Try to reset NVRAM which could solve the boot issue.
