MacBook Pro retina 15 inch mid 2012

Tried the following:
- Command + R: reinstalled Catalina but same thing happens.
- Command + option + R: same as above
- Command + shift + option + R: gives me the option to reinstall OS X but there is no drive showing up to install it on.
- Option/Alt with older OS on HDD plugged in: Tried High Sierra and Mojave one at a time. This external HDD doesn't show up in the volumes upon booting.
- First Aid shows no errors
