If I change the Startup disk to be my El Capitan partition on the external drive, that will work, but then there's no way to revert, because El Capitan won't recognize the internal hard disk as a bootable disk, so I won't be able to choose it. Now: if I succeed in installing Catalina on my internal hard disk, and boot from it, all is well. But, when I reboot back into El Cap from the internal hard disk, then it doesn't recognize the new install, doesn't mount the partition, can't select it as a Startup disk, and Disk Utility doesn't even show it as a formatted partition - simply refers to it as "Untitled". #Startup manager mac install#So, if for example, I'm running El Cap on my internal HD, and I install Catalina on an external disk partition, it will work, and reboot and run off the external partition. That means that if I install Catalina on an external drive partition, El Cap won't see it because it doesn't recognize the partition FS. The thing is, Catalina uses APFS, whereas El Cap is still using HFS+.

I booted up my El Cap system on my external hard disk, erased the internal hard disk using Disk Utility, and ran the Catalina install app from the Ep Cap system, telling it to install to "Macintosh HD".
