I am new with Raspberry Pi. I wrote the .img file onto my SD Card with DiskImager on Windows 7. I downloaded the 2013-09-25-wheezy-raspbian.img file from the Raspberry Pi website.

When I start the Raspberry Pi device, some instructions appear on display and suddenly after a few seconds it starts again. Then again it shows the same behavior.

I have version of Ubuntu 13.04 and I want to write .img file on SD Card. usb-imagewriter is not working for this. Can someone guide me to install Raspbian OS completely on my SD card?

I attached two picture,second picture show those instructions which execute and display. After these instruction , suddenly it restart again and show same behavior again and again. This picture show the Raspberry Pi in running state

Only these instruction appear and it suddenly restart Firstly I use my previous SD Card and then I purchase new SD Card pics given below: new SD Card power cable I use new SD Card and power cable given in picture.

I changed the title to reflect what you ask in your question, but you changed it back so that they conflict. What is your real question? Do you want to install Raspbian, or Ubuntu? –  syb0rg Nov 27 '13 at 19:13
    
My answer still covers both questions, so please take a look at it. –  syb0rg Nov 27 '13 at 19:14

use photo or video camera to capture the error message that shows on the screen, and paste it (just type the text, we don't need the whole picture/video) into your question. that should help greatly. –  lenik Nov 27 '13 at 23:37
    
The second picture is too far out and too blurry to discern the text easily. –  syb0rg Nov 28 '13 at 18:57

Even magnified that image is totally unreadable! What is the point in posting that? If you can't be bothered to either post a clearly readable image, or copy it by hand, don't expect anyone to bother to help you. –  goldilocks Nov 28 '13 at 20:40

I have version of Ubuntu 13.04 and I want to write .img file on SD Card.

From linux it is pretty simple. You get the zipped raspbian image from here (under "Raw Images", "Raspbian" -> "2013-09-25-wheezy-raspbian.zip"). Then:

unzip 2013-09-25-wheezy-raspbian.zip

Which leaves a file, 2013-09-25-wheezy-raspbian.img. Now, figure out which device node your SD card is. It will probably be, e.g., /dev/sdb or /dev/sdc. It is not /dev/sdb1 or /dev/sdc2, etc. Those are partitions on a device -- you can tell because they end with a number. Do not write to a partition, write to the entire device (sdb, not sdb1).

dd if=2013-09-25-wheezy-raspbian.img of=/dev/sdc bs=4M

That'll take a while. When it's done, it's done.

Unfortunately, from the glimmer in the photo in your post, it looks like you did write an image and it did mostly boot. What happened after that is unclear because the picture is unreadable.

I would recommend using the NOOBS software. It is easier than installing an OS manually. All you need to do is:

  1. Format your SD card using the SD Card Association’s formatting tool.

  2. Download and unpack the NOOBS zip file onto the SD card


There are multiple problems that could cause the error you are experiencing. One of these problems could be a faulty SD card. You should verify your SD card works with this list. There could also be a problem with your power supply. Make sure the power to your Raspberry Pi is adequate to boot properly. Another possibility is that your .img file was corrupted on download (this is the most unlikely, but is an option).

My power cable cause problem. It show 4.3mA but it must between 4.7mA to 5.2mA.When I increase the rate of power ,it works fine. –  Zeb Nov 30 '13 at 11:51
