Grey pixels do not mean no data. Did you check the values of random 
pixels with the Info tool?

Normally in the raster properties you have ask QGIS to calculate the 
range of values, and stretch min/max in order to actually see what you 
expect, or put in a custom color ramp.

Also what tutorial did you follow and which tool did you use to 
calculate the distance grid.
