First, turn your shapefile into a geotiff. You can do this by reading the
documentation and searching google for "gdal_rasterize".
You'll need to tell it what size you want to burn. You can do that by looking
at the extents (northeast, southwest) of your current raster/geotiff.
Second, overlay the 'shapefile geotiff' onto the other geotiff.
To do this, read the documentation for
gdal_merge.py or gdalwarp
Both of them can do what you want.
And look for some online articles about those tools for practical examples.
For example, read this and try to practice it:
