Can I run a different operating system such as Raspbian or Ubuntu on the Kano Computer Kit/Computer Kit Complete/Computer Kit Touch?
Kano OS is installed on a micro SD card and the Computer Kit series is built around the Raspberry Pi.
This means you're free to overwrite this with any operating system you want (or get additional cards and swap to your heart's content), but do keep in mind, that while other operating systems may run very well on the Computer Kit, the only support we can offer is for Kano OS.
You can find out more about Kano OS, Raspbian and Linux here.
