My Raspberry does not boot anymore to Raspbian.

I have installed it with NOOBS and it still boots NOOBS.

I could reinstall with NOOBS but NOOBS recognizes an installed version of Raspbian on the Pi.

But it does not boot it. How can I boot the obviously installed version of Raspbian? I'm confused. Could this be a error on the SD card?

(Red-LED is constantly on and Green-LED of after the startup process)


I think the best thing to do is to get a new sd card .. and reinstall. The sd card is the weakest link.

Use the SD formatter tool from here to format it. To mount the raspberian iso use etcher. You can get it here. Sometime you have to unplug and plug it back in after the first boot to get it to boot to a terminal/desktop.

  • Sorry this does not answer the question. SD card works (NOOBS runs on it). I don't want to format it. I googled the problem and everyone just says to format the SD card but the card works. It has no error. – Reto Weber Sep 11 '17 at 9:34
  • I have had a couple of SD cards that fail, but can still be read from but cannot be written to. It simplest solution will be to reinstall raspberian from the noobs boot menu. They may have been an error when you ran an update or the SD card failed. Can you read any of the partitions of the SD card in another computer? – Blake Sep 11 '17 at 10:23
  • @RetoWeber Most SD Cards have an automatic error correction to replace corrupted cells so they never report errors to the operating system even if they can't correct errors. – Ingo Feb 11 at 18:41
