I have downloaded the El Capitan dmg file (InstallMacOSX.dmg) provided by Apple. The expanded dmg image contains the package 'InstallMacOSX.pkg' which should be run to create the El Capitan installer but fails with the following message 'This version of OS X 10.11 cannot be installed on this computer.' presumably because quite reasonably it would not make sense to install on top of a later version of the OS. However in this case I want to create a boot USB drive for an installation on another Mac.
I am stuck in a chicken and egg situation where I need another machine running El Capitan or earlier to create and El Capitan boot installer.

- With the release of El Capitan, Apple took the opportunity to give Disk Utility a facelift. You can still use the software to format a startup drive—it’s similar to the steps in the previous.
- To create a bootable El Capitan installer drive, you need the El Capitan installer from the Mac App Store and a Mac-formatted drive that’s big enough to hold the installer and all its data.

From this point, we've now provided plenty of installation files whether for installing macOS on Windows or on Mac. Such as macOS Sierra DMG, macOS High.
