The SD card is not being read properly.
Is it properly inserted?
How are you writing the image to the card? What filesystem is the card formatted as?
The preloaded NOOBS card from element 14 was inserted correctly for sure and did not work. A separate card, as noted, was formatted with the formatting tool suggested on the website, as FAT 32, and I copied the latest NOOBS release , unzipped, onto that card. It also did not work.
Here is an abstract form the NOOBs documentation. Display Mode Selection: By default, NOOBS will output over HDMI at your display's preferred resolution, even if no HDMI display is connected. If you do not see any output on your HDMI display or are using the composite output, press 1, 2, 3 or 4 on your keyboard to select HDMI preferred mode, HDMI safe mode, composite PAL mode or composite NTSC mode respectively. https://github.com/raspberrypi/noobs/blob/master/README.md#about Hope this helps
I suggest you to try at least the HDMI safe mode
Personally I found the Rasbian stuff easier to get working as you do not need to reformat it first, just use DD to copy the image directly to disk!
Thanks to all who responded to my original post. Found the problems; there were two:
1. The NOOBS card from element 14 was faulty.
2. The card I prepared myself needed to have the unzipped files outside of the NOOBS folder to work; then it booted.
it will boot only if u are using the updated version of image files or noobs.
i have posted the detailed setup of raspberry pi without screen,mouse and keyboard to this link u can refer it.....
I got a Raspberry pi B+ and preloaded NOOBS 8GB micro sd card from Element 14, inserted the card, connected the HDMI cable, mouse, and keyboard. When I supplied power (unit made specifically for the pi, 5V 1amp), both the red and green lights both come on and stay on (full brightness), neither flash, and I get nothing on the TV. Thought it might be a bad card, so I purchased a class 10 sd card, formatted (FAT32) it with the suggested software, downloaded the NOOBS and copied it to the card, and got the same (no boot) result. Also tried having nothing connected when I supplied power, but got same result again. Suspect the pi is bad; any help appreciated.
