7.5b2 - Can I load sample data later, if it failed to load at install time?

BTW. install was OK but no dummy data loaded even though I ticked “install dummy data”.

Can I do it post-install?

Not a standard feature, you would have to re-install. You can simply remove the config.php file and re-run the installer.

Just FYI, I just tried doing this on 7.5.3 and it re-installed but didn’t load sample data. Maybe I did something wrong or needed to delete the database tables?
