how to get rid of the recovery partition?

hello, i'm trying to downgrade my macbook pro mid 2012 from high sierra back to os x mountain lion which was the os it shipped with. i erased my drive and went into internet recovery, but for some reason it's always showing the recovery for catalina. also, for some reason, the os x recovery drive for high sierra is shown as the only bootable drive and i don't know how to get rid of it. i think it's barring me from reverting back to the factory version. please help me! thank you

To access the online Mountain Lion installer you need to boot into Internet Recovery Mode using Command + Option + Shift + R.

While booted to the installer you will need to partition the whole physical drive as GUID partition and MacOS Extended (Journaled) using these instructions:

If your laptop is able to boot normally or into Safe Mode or you have another compatible Mac, then you can create a bootable macOS USB installer for macOS 10.11 to 10.15 using the instructions in this Apple article:
