The default boot time of 300 seconds is not long enough for the initial installation, especially on Windows which is particularly slow at running virtualbox if you have Hyper-V active. In such cases the initial installation seems to take upward of 15 minutes.
This results in a warning, but doesn't appear to break anything.
To avoid this, the config.vm.boot_timeout value could be changed to 1800 (30 minutes).
