The big news about the Raspberry Pi 3 was built-in Bluetooth and Wi-Fi, but it turns out there was another set of new tricks: New boot options. This feature’s still in beta, but over at the Raspberry Pi Foundation, they outline how to boot from a mass storage device or over ethernet. Right now, they’re still working out some quirks, but you can edit a TXT file to enable the new boot modes. This means the Raspberry Pi 3 can boot from a flash drive or a USB hard drive instead of a SD card. This will likely be a little slower than the SD card, but it’s still useful for those of us with a ton of extra flash drives sitting around. There’s also ethernet support for network booting built in there too. This is all still in beta and a little unpredictable, but if you don’t mind toying around with experimental features, you’ll find everything you need over on GitHub.
