2009 iMac
I want to restore my 2009 iMac (still working ok) to factory settings but I no longer have the Boot Disc. Any suggestions please?

Question marked as
Is it an Early 2009 or Late 2009?
- You can not restore either to the factory settings without the original gray Disk Set.
- You can use a Snow Leopard Upgrade DVD on an Early 2009, the Late 2009 may require Lion.
- If it is a Late 2009 that was running High Sierra, then you should be able to use macOS Recovery to reinstall High Sierra.
