Learn how to upgrade to macOS Big Sur, the latest version of macOS.
Check compatibility
If a macOS installer can't be used on your Mac, the installer will let you know. For example, it might say that your Mac doesn't have enough free storage space for the installation, or that the installer is too old to be opened on this version of macOS.
If you want to check compatibility before downloading the installer, learn about the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan, or Yosemite. You can also check compatible operating systems on the product-ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini, or Mac Pro.
Make a backup
Before installing, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Learn how to back up your Mac.
Download macOS
It takes time to download and install macOS, so make sure that you're plugged into AC power and have a reliable internet connection.
These installers from the App Store open automatically after you download them:
- macOS Catalina 10.15 can upgrade Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks
- macOS Mojave 10.14 can upgrade High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion
- macOS High Sierra 10.13 can upgrade Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion, Lion
Your web browser downloads the following older installers as a disk image named InstallOS.dmg or InstallMacOSX.dmg. Open the disk image, then open the .pkg installer inside the disk image. It installs an app named Install [Version Name]. Open that app from your Applications folder to begin installing the operating system.
- macOS Sierra 10.12 can upgrade El Capitan, Yosemite, Mavericks, Mountain Lion, or Lion
- OS X El Capitan 10.11 can upgrade Yosemite, Mavericks, Mountain Lion, Lion, or Snow Leopard
- OS X Yosemite 10.10can upgrade Mavericks, Mountain Lion, Lion, or Snow Leopard
Install macOS
Follow the onscreen instructions in the installer. It might be easiest to begin installation in the evening so that it can complete overnight, if needed.
If the installer asks for permission to install a helper tool, enter the administrator name and password that you use to log in to your Mac, then click Add Helper.
Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs both macOS and related updates to your Mac firmware.

You might also be able to use macOS Recovery to reinstall the macOS you're using now, upgrade to the latest compatible macOS, or install the macOS that came with your Mac.
Not too clear on just what you have done, but if you reformatted the disk at some point, you may have erased the Recovery HD on the disk itself. So that would leave you having to try Internet Recovery (Option-Command-R) to install the original OS.
The problem may well be that Lion is not the original OS. This Mac originally shipped with Snow Leopard install discs, which you do not have. It did not originally ship with Lion, so there may be some issue there which is keeping you from completing the installation of Lion using Internet Recovery since Internet Recovery is intended to install the OS the Mac originally shipped with.

Are you wanting to sell or give away this Mac? If so, it needs to have the OS it originally shipped with installed, which would be 10.6.6 or 10.6.7 Snow Leopard. If you have access to an Apple Store, they could probably do this for you from their store feed. Snow Leopard can be updated to where the Mac App Store is available, and the new owner can install anything they want under their own Apple ID. This Mac can be upgraded to run Sierra.
I don't know if replacement install discs are still available from Apple for this Mac, but if you can get it done for free at the Apple Store that would be a better option for you.
Good luck!
