SystemDisc is a general-purpose tool for managing the system software on modern RISC OS systems. Start with a blank formatted SD or SDHC card. Method 3: Preparing the media manually ( RISC OS only) IMG file, so there is no advantage to using large-capacity cards. Unpack the archive, then use a utility such as Win32DiskImager (Windows) or Etcher (Linux/macOS) to copy the image to the MicroSD card 1.ġ RISC OS will only be able to use the space occupied by the. Method 2: Preparing the media using a pre-built SD card imageįirst, download a suitable SD card image such as “ RISC OS Pi” (available on the Downloads page – this will fit on a 2GB card). This process will take approximately 4 minutes. This will write the image to the SD card and then verify that the image was written properly. An SD card of at least 2GB is required (if you use a larger card, RISC OS will only be able to use the first 2GB). Click on “Choose SD card” and select the device to use.If more than one RISC OS version is offered, select “ RISC OS 5.28”. Start Raspberry Pi Imager, click on “Choose OS” and select “ RISC OS Pi”.
Install Raspberry Pi Imager onto a Windows/macOS/Linux computer.This downloads the software and writes it to the SD card in a single process. The easiest method is to use Raspberry Pi Imager (Windows/macOS/Linux) to install RISC OS version 5.28. Be aware that some cards sold as Sandisk are counterfeit: if in doubt, buy from a reputable supplier. SD cards up to 32GB capacity can be used, but it may be worth checking the known good cards list as there have been problems with a few cards. The instructions given below will work on models of Raspberry Pi up to and including the Pi 4B and Pi 400.
