macOS Ventura not downloadable to run on a separate disk from App Store, wants to update instead, so the instructions here don't work: Use more than one version of macOS on a Mac - Apple Support
Tried installassist, but that says "can only be installed on the disk running MacOS"
help?
This worked for me, then I didn't need to create a partition, just a volume: https://forums.macrumors.com/threads/macos-ventura-directly-installed-on-monterey-no-option-for-second-partition.2347903/?post=31179663#post-31179663

You would need to partition your drive.
If you're seeing, "can only be installed on the disk running MacOS," then you've mistakenly downloaded and update instead of a full installer.
how do I keep Monterey running and install Ventura fresh on the same Macbook?
