When prompted, make the current user the owner of the external bootable system.

Run the installer, and point it at your external disk when it asks you where you want to install macOS.

If the fault or failure is so great that it can’t be put into Recovery, then you’re most unlikely to be able to get it to boot from an external disk, and will either have to put it into DFU mode for a refresh or restore using Apple Configurator 2, or hand it over to an Apple technician to diagnose.
