Cant reinstall mac os to my mac
So, in my mac, I don't have an os. I think I tried every way to fix it. I tried to boot from a USB but my mac sees USB in Disk utility in recovery mode but not on starup. I tried reinstalling OS X but I see the macOS Installation Couldn’t Be Completed. And now when I try to reinstall I can't see my hard disk. I really don't know what to do and really need help. I hope someone can help me...
