From the
Raspberry Pi download page and shortened!
- Noobs - A way to try all the main ones in one re-imagiable download.
- Raspbian “wheezy” - Recommended, with development tools.
- Soft-float Debian “wheezy” - Same as Raspbian but compiled for the slower soft-float hardware. Used for Oracle JVM version 7 or less.
- Arch Linux ARM - Boots in 10 seconds but definitely not for beginners.
- Pidora - Fedora.
- RISC OS - Acorn.
