StartOS (Raspberry Pi)

This guide is for flashing StartOS to a microSD card in order to install it on a Raspberry Pi.


If you are running in a “Lite” configuration (everything on an SD card), then flashing that SD card in the manner proscribed below WILL ERASE ALL YOUR DATA! If you need to reflash and you are NOT using an external SSD (ie. you have a Server Lite), please contact support for assistance instead.

Getting StartOS

Visit the Github release page to find the latest StartOS release.

At the bottom of the page, under “Assets,” download the startos-..._raspberrypi.img.gz file.

(Optional, but recommended) Verify the checksum against the one listed on GitHub (SHA256):

Installing StartOS

Once you have the StartOS .img.gz file, you will need to flash it onto a microSD card.

  1. Download and install balenaEtcher onto your Linux, Mac, or Windows computer.

  2. Insert the microSD card into your computer, either directly or using an adapter.

  3. Open balenaEtcher.

    Balena Etcher Dashboard
  4. Click “Select Image” and select the .img.gz file.

  5. Click “Select Target” and select your microSD card.


    BE ABSOLUTELY CERTAIN you have selected the correct target microSD card. Whatever drive you select will be COMPLETELY ERASED!!

  6. Click “Flash!”. You may be asked to approve the unusually large disk target and/or enter your password. Both are normal.

  7. After the flash completes, you may remove the newly flashed micro SD card from any adapter, and insert it into your server’s SD card slot.

  8. Finally, continue to the Initial Setup, Manual Update, or Reset Password instructions - depending on your need.
