So my friend has a 2011 MacBook Pro. The laptop's hard drive crashed and no longer works. He bought a new SSD as a replacement, but he doesn't have a way to install macOS on this new SSD, because he cannot create a bootable USB from his old hard drive.

I have a 2009 MacBook Pro running OS X El Capitan on it. Can I use my MacBook Pro to create a bootable USB with OS X El Capitan on it? So my friend can use this bootable USB to install OS X El Capitan on his MacBook Pro.

Hold the keys until the animated globe appears on the screen. “Starting Internet Recovery,” the message reads." Commented Apr 2, 2019 at 17:53
