Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Open Disk Utility, select the Macintosh HD volume, open the erase tab, and press the erase button. Quit Disk Utility and choose Install OS X. See If your Mac came with Lion, the Install OS X option will download and install the latest minor version of Lion. Jun 04, 2020 Mac OS X Lion was released in 2010. Being such an old operating system, you probably don't want to install it directly onto you computer. But you may still want it on an external drive to use programs that don't work on new operating systems, or to 'remember the good old times.'
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.

Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your external hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possiblebecause it is three times faster than wireless.

In theory, you should have to install Mountain Lion only once, or never if your Mac came with Mountain Lion preinstalled. And in a perfect world, that would be the case. But you might find occasions when you have to install/reinstall it, such as
- If you get a Mac that didn’t come with OS X Mountain Lion preinstalled
- If you have a catastrophic hard-drive crash that requires you to initialize (format) or replace your boot drive
- If you buy an external hard drive and want it to be capable of being your Mac’s startup disk (that is, a bootable disk)
- If you replace your internal hard drive with a larger, faster, or solid state drive
- If any essential OS X files become damaged or corrupted, or are deleted or renamed
