The method uses a Linux computer for setting the Raspbian image on the microSD card (Raspbian changes shown here could just be deferred on a headed Pi). You need the Pi, not yet powered-up, connected to your network plus a SD card + USB adapter; the latter just for interfacing the SD card to the Linux computer if it has no SD card slot.
Note: for this example method the network (192.168.0.0) has connected: a Windows computer (with PuTTY and Xming installed), raspberrypi (will be set to 192.168.0.6) and an internet gateway machine/firewall/router (192.168.0.5). A Linux computer is also needed, but it does not have to be on the 192.168.0.0 network. You will have to adapt things to suit your configuration.
Some of the window captures below may not exactly match what you now see with the latest Raspbian "jessie" (with PIXEL) image.
Note: commands shown ($ 'command') in this section are for the Linux computer.
- Download Raspbian "jessie" 2017-04-10-raspbian-jessie.zip to, for example, a Linux computer directory /scratch (the zip is a 1.45GB download and the extracted image, for the microSD card, is 4.18GB). Note: the microSD card needs to be 8GB or larger and not partitioned.
$ cd /scratch $ sha1sum 2017-04-10-raspbian-jessie.zip 6d7b11bb3d64524203edf6c80c499456fb5fef53 2017-04-10-raspbian-jessie.zip $ unzip 2017-04-10-raspbian-jessie.zip Archive: 2017-04-10-raspbian-jessie.zip inflating: 2017-04-10-raspbian-jessie.img
- Plug your microSD/adapter into the Linux computer (best to reformat the SD card first). Find the device that is your SD card
$ fdisk -l ... Device Boot Start End Blocks Id System /dev/sdc1 8192 62333951 31162880 c W95 FAT32 (LBA)shows a /dev/sdc1 partition, for me, and a 32GB card (but check really carefully you get the right device + the SD card is about to be imaged and all its original contents lost!)
$ umount /dev/sdc1 umount: /dev/sdc1: not mountedjust in case it is mounted and copy the image to the SD card (takes a while, go and put the kettle on)
$ dd bs=4M if=2017-04-10-raspbian-jessie.img of=/dev/sdc 1021+1 records in 1021+1 records out 4285005824 bytes (4.3 GB) copied, 322.809 s, 13.3 MB/sNote: use of device: /dev/sdc, not the first partition on the device: /dev/sdc1.
$ syncto flush system buffers before removing the SD/adapter.
- You can see the Raspbian partitions on the SD card
$ parted -l ...

- Unplug the SD/adapter and plug it back in again. The new partition will not mount if you don't do this.
- Mount partition /dev/sdc2 and go to the location of the files to be changed
$ mkdir /media/external if the directory /media/external does not exist $ mount -t ext4 /dev/sdc2 /media/external $ cd /media/external/etcI'm going to set the interface on the Pi to be static address: 192.168.0.6, and the internet gateway: 192.168.0.5.

Get out of the mounted partition and dismount it
$ cd $ umount /media/external
$ ping 192.168.0.6Ping should respond on the Pi itself and elsewhere on the network (and where named to: raspberrypi).
I clean SD cards with the official SD Association formatter, before reusing them, as it removes any partitions automatically.
Note: commands shown ($ 'command') in this section are for your Pi via PuTTY on Windows.
- Run PuTTY.exe on your Windows computer.
Enter the address of raspberrypi (192.168.0.6 in this case), set/check the remote character set is UTF-8 and click 'Open'.
Click 'Yes' to the PuTTY Security Alert...we do trust this host!
- At the PuTTY terminal prompt respond pi to 'login as:'
and raspberry to 'firstname.lastname@example.org's password:'
You should now have a command line terminal for pi@raspberrypi:~
Enter: sudo raspi-config
Security note: you really should change the default password for the 'pi' user if you are using a public network.
You need to '1 Change User Password, set '3 Boot Options' ('B1 Desktop / CLI' and 'B1 Console'), check/set '4 Localisation Options', run '7 Advanced Options' ('A1 Expand Filesystem') and run '8 Update'. Note: the default locale is for the UK. Re-run raspi-config again anytime you want to change these options and, if asked, allow the Pi to reboot.
- You should be on the internet (via your gateway) so do a full upgrade
$ sudo apt-get update $ sudo apt-get upgradeGo make coffee...upgrade may take some time!
You don't want all that login spam again and a reboot is now needed
$ touch .hushlogin $ sudo shutdown -r nowYour PuTTY terminal will disconnect, so close it, wait a while and reconnect with PuTTY when the Pi has booted (use ping to check it's up).
- Log back in to the PuTTY terminal for user pi.
Give root a password and remember it (optional...it's your Pi...you can reload the image yourself if you destroy it...plus you don't want to keep typing sudo to do useful work!)
$ sudo passwd rootBut I suggest you add (or enable) some aliases in ~/.bashrc for both user pi and root to protect yourself a little.

Logout the LXDE (Lightweight X11 Desktop Environment) session properly from the Task Bar (LXPanel) when finished.
Start an Xming multiwindow mode server
Xming -multiwindow -clipboardYou have used PuTTY above: time to add settings for SSH X11 forwarding
Now click Open and login as 'pi' as before. At the PuTTY terminal type
$ midori or the command to run another graphical application
The Midori browser will display (if it is installed), and interact with the user, on the Windows desktop
- Finally: I recommend you don't use startlxde or lxsession via PuTTY as you can't Logout cleanly and the Pi's resources may be left in unknown states (e.g. processes and files not gracefully flushed, stopped or closed).
