Hi @mark,
I’m not sure which version you were trying to install, but generally they should be able to start up. That said, we’ve just released BlueOS-1.1 stable, which should be more robust than the beta versions preceding it, so hopefully it works to update to that. If that’s also not successful then I’d recommend following the installation instructions to flash a 1.1 image directly onto a micro SD card that you then use in the Raspberry Pi
