What RISC OS version does latest NOOBS install? (Rpi)

Hi there,

I am considering configuring an SD card from NOOBS so I can have both RISC OS and Debian on the same card and I can switch between them by rebooting.
However, I would like to have the latest RISC OS version installed by NOOBS, and I am not sure that’s the case: last time I checked, NOOBS would install RC14, while RC15 is already available time ago.
So, how can I know what RISC OS version does NOOBS install currently?

Thanks

EDIT: I found out that NOOBS installs RC14 from 2015. Is there an easy way to overwrite it with my current RISC OS install?
The ROM/boot files part is easy, but the system partition is “UNKNOWK” to GNU/Linux, so I simply tried dd-ing the system partition from my current RISC OS SD install (which is RC15) onto the NOOBS-installed RISC OS system partition, but it does not boot after that.
