+We may want to install lubuntu desktop/server to SD card, here is a guide for you. This guide is for Linux platform only. We take Desktop as a example in this guide. If you are interested in Server, just replace the images with [[http://dl.cubieboard.org/software/a20-cubietruck/lubuntu/ct-lubuntu-card0-v1.00/server/|server one]].
 ===== Prerequisites =====
-   * Any Linux environment, we want sfdisk, dd, wget commands
+   * Any Linux environment, we want fdisk, dd, tar, wget commands
    * An SD Card(at least 2GB)
 ===== Installation ======
+We assume card=/dev/sdd here
-==== Download Images====
+==== Get Images====

-  * bootfs (partition 1)
+==== Cleaning SD Card ====
+  $card=/dev/sdd
+  $sudo dd if=/dev/zero of=${card} bs=1024 seek=544 count=128
-	 $wget http://dl.cubieboard.org/software/a20-cubietruck/lubuntu/ct-lubuntu-card0-v1.00/desktop/bootfs-part1.img.gz
+==== Make Bootable SD Card ====
-  * rootfs (partition 2)
+  $sudo dd if=u-boot-sunxi-with-spl-ct-20131102.bin of=$card bs=1024 seek=8
-	 $wget http://dl.cubieboard.org/software/a20-cubietruck/lubuntu/ct-lubuntu-card0-v1.00/desktop/rootfs-part2.img.gz
+==== Partitioning ====
-==== Extract the Images====
+  $ sudo fdisk $card
-	  $gzip -d bootfs-part1.img.gz
-	  $gzip -d rootfs-part2.img.gz
+Using the fdisk command to create 2 partitions on the SD Card, e.g.
+  * 1st partitions start from 2048 sectors, 64MB in size
+  * 2nd partitions just keep it all default
+Show bellow
+   Device Boot      Start         End      Blocks   Id  System
+  /dev/sdd1            2048      133119       65536   83  Linux
+  /dev/sdd2          133120    15278079     7572480   83  Linux
+Also we recommend you to look at [[http://linux-sunxi.org/Bootable_SD_card |Bootable_SD_card]]
+  $sudo mkfs.ext2 ${card}1
+  $sudo mkfs.ext4 ${card}2
-==== Create Partitions on SD Card ====
-	  sudo sfdisk --force --in-order -uS /dev/sdX <<EOF
-,24576,L
-	  ,,L
-	  EOF
-	/dev/sdX is the block device of your SD Card
-==== Write Images to SD Card ====
-	  sudo dd if=u-boot-sunxi-with-spl-ct-20131102.bin of=/dev/sdX bs=1024 seek=8
-	  sudo dd if=bootfs-part1.img of=/dev/sdX1 bs=1M
-	  sudo dd if=rootfs-part2.img of=/dev/sdX2 bs=1M
-	  sync
-===== Notes =====
-  * This guide is suitable for the ct-lubuntu-card0-v1.00 desktop/server images
+==== Copying ====
-  * The image default HDMI display
+  $mkdir /tmp/sdd1 /tmp/sdd2
+  $sudo mount -t ext2 ${card}1 /tmp/sdd1
+  $sudo mount -t ext4 ${card}2 /tmp/sdd2
+  $sudo tar -C /tmp/sdd1 -xvf bootfs-part1.tar.gz
+  $sudo tar -C /tmp/sdd2 -xvf rootfs-part2.tar.gz
+  $sync
+  $sudo umount /tmp/sdd1
+  $sudo umount /tmp/sdd2
+===== Customizing ( optional )====
+==== Change your own kernel ====
+==== Move Rootfs to Hard Drive====
+  * Mount rootfs partitions
+After login to lubuntu system on Cubietruck with linaro,
+  $sudo su - root   --> change to root user
+  #mkdir /tmp/1 /tmp/target
+  #mount /dev/mmcblk0p2 /tmp/1
+  #mkfs.ext4 /dev/sda1
+  #mount /dev/sda1 /tmp/target
+  * Moving rootfs
+  #(cd /tmp/1; tar --backup -c *) |tar -C /tmp/target -xv
+  * Changing Kernel Parameters
+  #mount /dev/mmcblk0p1 /mnt/
+  #vi /mnt/uEnv.txt
+  (Change root=/dev/sda1)
+So the file's content would like bellow
+  cat /mnt/uEnv.txt
+  root=/dev/sda1
+  extraargs=console=tty0 hdmi.audio=EDID:0 disp.screen0_output_mode=EDID:1280x720p50 rootwait panic=10 rootfstype=ext4 rootflags=discard
+  * Sync to disk, and reboot to your hard drive
+  #sync
+  #umount /mnt
+  #reboot
+After installing rootfs to SSD, we will get much more better experience.
+  * Performance (R:106MB/s, W: 148MB/s)
+  root@cubietruck:~# cat /sys/block/sda/device/model
+  SAMSUNG SSD 830
+  root@cubietruck:~# dd if=/dev/sda2 of=/dev/null bs=1M count=10000
++0 records in
++0 records out
+  10485760000 bytes (10 GB) copied, 98.9637 s, 106 MB/s
+  root@cubietruck:~# dd if=/dev/zero of=/dev/sdb2 bs=1M count=5000
+  dd: writing `/dev/sdb2': No space left on device
++0 records in
++0 records out
+  956919808 bytes (957 MB) copied, 6.45456 s, 148 MB/s
 ===== Tips =====
 ==== VGA output ====
+If we want to change to VGA output default, we need to modify the script.bin at the 1st partition
+  $bin2fex script.bin 1.fex
+  $vim 1.fex (and change screen0_output_type to 4)
+  $fex2bin 1.fex script.bin
+====Kernel Source====
+  * http://github.com/cubieboard/linux-sunxi (cubie/sunxi-3.4 branch)
+====Wifi Module====
+Cubietruck have AP6210 wifi/bt module combo on board, to load the module,
+  #modprobe bcmdhd
+====Default User/Password====
+  linaro/linaro
