This error raises because BMP format does not support storing
projection information. Not all formats has equal capabilities
for storing georeferensig. You may ignore this error (I think,
you don't need projection info if you are choose BMP as an output
format). Otherwise, if you want preserve this data, you need other
format. GeoTIFF is the most powerful, flexible and portable on present
moment, I'm suggest use GeoTIFF for all operations. Note, that if you
say

gdal_translate -of GTiff -ot Byte -scale <infile.tif> <outfile.tif>

you will get a scaled GeoTIFF file, which should be supported by many
image viewers.
