CREATE A MULTIBOOT IMAGE WITH PINN
Select an SD card size
Multibooting your Raspberry Pi doesn’t have to rely on BerryBoot or any other downloadable tool. With PINN, you can manage it all in your browser. You’ll find the PINN tool at https://pinn.mjh.nz, where you’re immediately prompted to select your storage device and capacity. You can choose an SD card, USB storage or a mix of both; note that 100MB is reserved for the PINN software.
Set your system sizes
Your chosen operating systems each require enough space to run effectively. You can help here using the slider to determine how much disk capacity each operating system partition will have. With two operating systems, there’s a single slider; three OSes means two sliders, and so on. Adjust the slider as necessary, ensuring that each OS you have chosen has enough additional storage space.
Choose your Pi model
With the correct media and capacity selected, choose the Raspberry Pi board you’ll be using. Every option is available here, covering A boards, B boards, Zeros and Compute Modules, so choose the correct model with care. There are differences between standard and plus (+) models, so be sure to make the right choice here. If you misclick at any point, simply click Back to retry.
Download your disk image
After clicking Next, download PINNlite using the button, along with a file called recovery.cmdline. This shouldn’t take too long. With your media attached to the computer, unzip PINN and then copy recovery.cmdline into the pinn-lite directory, overwriting the existing file. This file includes instructions for downloading and installing your chosen OSes and partition size.
Choose operating systems
Next, select from one or more operating systems for the Raspberry Pi, arranged by type. The choice covers minimal systems, gaming, utilities, testing, general operating systems and media centres. Click an OS to select it for your multiboot system; click again to deselect. Watch the Required figure at the top of the screen, and ensure that it stays below the Available capacity. Click Next to continue.
Create your multiboot Pi
Finish by copying the contents of pinn-lite to your selected Raspberry Pi media, then safely ejecting. Power up to load the PINN environment, then connect the Pi to the network, either using Ethernet or press W to configure Wi-Fi. Select your intended operating systems, click Install, and wait for installation. When the device reboots you’ll see a boot selection screen, ready for your choice.
