WRITE INSTRUCTIONS

How to write the operating system’s .img file to a micro-SD card (8GB minimum), suitable for booting a Raspberry Pi microcomputer. A good SDHC class 10 card is highly recommended.

1. Extract the .img file from the downloaded ZIP archive.

2. Write the image by the use of Etcher. Make use of a micro-SD to USB key adapter for the write process.

Linux operating system specific
Linux users can also make use of dd.
Run all the following commands as root or with sudo in a terminal emulator:

  • plug the SD card into your PC;
  • use fdisk -l for locating the device file, for example: /dev/sdx (change for your case);
  • it’s better to unmount the auto-mounted device’s partitions, if any (umount /dev/sdx1, umount /dev/sdx2, …);
  • finally write the image: dd if=path/to/imageFile.img of=/dev/sdx bs=50M
  • please note that the dd command must refer to the whole disk: do not use /dev/sdx1 but /dev/sdx, as an example.

 

First boot

Once you have successfully written the IMG file to the micro-SD, plug the card into the R-Pi and reboot the microcomputer.

 

Notes

  • I see a coloured square/lighting bolt near the top right corner of the screen.
  • Louis DeRobertis reports that some HDMI to VGA converters do not give enough power to the screen – it will remain blank.
  • Never halt or reboot the Pi by powering it off (some Raspberry Pi boards are reported to be prone to filesystem corruption); use SSH instead (with the halt or reboot commands).

    You can of course schedule a cronjob which will turn off or reboot the Pi gracefully as well.
