I’m running monterey and need to make a bootable install/recovery disc for a el capitan system. I did a wipe disc instead of a fresh install I would prefer to recover the old OS, bookmarks, files etc, but ultimately, I just want to make it usable again. I have the el capitan installer downloaded and a couple of USB drives. The instructions i’ve found for terminal, seem to discribe and elcapitan system creating a boot disc and not a later OS evolution.
From where did you download the installer? It sounds to me like you may have downloaded an update installer from support.apple.com/downloads. That is not the correct software you want for this task.
The proper download to use for creating a bootable USB installer is this: El Capitan 10.11
That is the same link that is found in this Apple support doc:
How to download and install macOS - Apple Support
With that correct download and the guidance from the document above, you should be able to create your bootable usb drive. The correct format to start with on that drive is as BDAqua has posted above: Mac OS extended (journaled) with GUID Partition scheme.
EDIT - to add, the correctly downloaded El Capitan file is "InstallMacOSX.dmg" and should be about 6.2GB in size.

Download and in install El Capitan to an external External Hard Disk then back up hat up with Carbon Copy Cloner or SuperDuper! And you are done.
Mac OS extended (journaled), GUID Partition scheme is required.
Thanks for your reply.
I’ve tried installing on both USB drives and it won’t let me. I’ve reformatted to the newer fat protocol…
it only took a second to “wipe the disc”. What happened to norton utilities or disc doctor?

many others have advised ExFAT, which I tried, also FAT, Mac OS extended (journaled) and Mac OS extended (case sensitive, journaled). None of which have made any difference. OS X installer gives me the message “OS X can’t be installed on this disc.mac OS isn’t installed”.
Your formatted the External Hard Disk incorrectly, FAT is for PC's not for Mac OS.
Software package is “InstallMacOSX.pkg”. Checked the info box, says “software update”. Is this the correct download?
Either drive works fine with time machine. No problem there.
Bootable install disc for el capitan?
