I am a real newbie on QGIS and wanting to draw contour maps from satellite, following the youtube videos. So now I have a table with all data, and following the video, I should use the SAGA tool GRID (natural neighbour) tool but can't find it on the toolbox.

Can anyone help me?

You may use the simplified interface in Processing toolbox as you can see in the red box below:

You need to change it yo advanced interface, and you find SAGA tools as well as other tools, but you mau need to install the other tools separately:

If turning the interface from simple to advance didn't solve your problem, then make sure that SAGA installed in your system. You can have a look at how to configure external tools in QGIS for more information.

  • Try to install QGIS from OSGeo4W from http://qgis.org/en/site/forusers/download.html. There are 32 bit and 64 bit. You can choose the express desktop installation and follow the steps. Then, see if reinstalling QGIS fixes the processing toolbar. – ahmadhanb Jun 01 '16 at 05:24
  • It took me quite a while as I was absent, in Africa, in a project, and just came out. The SAGA tools now appear with the heading (SAGA 2.1.4 235 algortihms. – Joao Serras Pereira Aug 06 '16 at 13:27
  • It took me quite a while as I was absent, in Africa, in a project, and just came out. However in spite many saga tools show (its version 2.1.4) the grid algorithms do not show – Joao Serras Pereira Aug 06 '16 at 13:29
  • Do you have the Raster tools instead? – AndreJ Jun 12 '17 at 05:23
