Hello daschrislydon,

Thanks for reaching out to the Apple Support Communities! From your message I can see that you have erased the 2011 MacBook Air and are looking to upgrade the OS X from Lion.

You're correct that you need to upgrade to OS X El Capitan before you can upgrade to macOS High Sierra.

Since you're unable to reinstall the Mac OS X Lion through Recovery, see if you can boot into Internet Recovery. To access Internet Recovery, restart your MacBook Air and hold down Option + Command + R. This will allow you to reinstall OS X Lion.

By reinstalling Lion you'll have access to the App Store and you can follow the steps to upgrade to OS X El Capitan: How to upgrade to OS X El Capitan.

Once you have OS X El Capitan running, you can then upgrade to macOS High Sierra: How to upgrade to macOS High Sierra.

If you're unable to reinstall OS X Lion, you'll need to have access to another Mac to be able to create a bootable USB drive for El Capitan. This article will provide you with the steps to take to create a bootable installer: How to create a bootable installer for macOS.

All the best!

Is your Mac up to date with the latest version of the Mac operating system (macOS or OS X)? Is it using the version required by some other product that you want to use with your Mac? Which versions are earlier (older) or later (newer, more recent)? To find out, learn which version is installed now.

If your macOS isn't up to date, you may be able to update to a later version.

Which macOS version is installed?

From the Apple menu  in the corner of your screen, choose About This Mac. You should see the macOS name, such as macOS Mojave, followed by its version number. If you need to know the build number as well, click the version number to see it.

This example shows macOS Catalina version 10.15 build 19A583.
