Comment 2 for bug 1844968

If you are installing an AIO (All-in-one) system on baremetal or virtual-env, you need to choose the menu option related to the All-in-one Controller configuration:
     Select ‘All-in-one Controller Configuration’

For AIO-simplex (1-node):
https://docs.starlingx.io/deploy_install_guides/current/bare_metal_aio_simplex.html

For AIO-duplex (2-node):
https://docs.starlingx.io/deploy_install_guides/current/bare_metal_aio_duplex.html

The "Standard Controller Configuration" is for multiple nodes (controllers + worker nodes and optionally storage nodes). The error returned indicates that a storage node or a worker node should be configured as well.

Are you saying the ‘All-in-one Controller Configuration’ is not available from the installer menu for your system? If so, what hardware are you using? Are you installing with legacy mode BIOS or UEFI?
