You created an unprojected location which is unsuitable for your
UTM GeoTIFF below.

In GRASS >=6.3 there is a new location wizard available which greatly
helps (not sure if working on Windows already). In general, creating an
UTM 34 location is fairly easy. Then import the map into it.

If it had complete metadata, you could generate the location directly
from the GeoTIFF.
