Working with AIG Raster format in ArcGIS for Desktop? [duplicate]

This question already has an answer here:

• Identifying Coordinate System of Shapefile when Unknown? 10 answers

I downloaded a specific layer which has the format "AIG" as you can see in the screenshot.

It has no projection so I applied "Define Projection" on it. I searched for the projection and found the following:

4.1 - INDIRECT SPATIAL REFERENCE SYSTEM:

Type of indirect spatial reference system:

By country.

Reference date: 2001.

4.2 - DIRECT SPATIAL REFERENCE SYSTEM:

Datum: Lambert Azimuthal.

Ellipsoid: Sphere.

Map projection: Projection LAMBERT_AZIMUTHAL

Units METERS

Spheroid SPHERE

Major Axis 6378388.00000

Minor Axis 0.00000

Parameters:

radius of the sphere of reference 6378388.00000

longitude of centre of projection 9 0 0.000

latitude of centre of projection 48 0 0.000

false easting (meters) 0.00000

false northing (meters) 0.00000

The problem I have is that if search for this projection I get these two

After applying the first one using "Define Projection", nothing changes in the file. By this I mean the spatial reference is still "undefined" and the coordinate system is unknown. I also tried other projections but nothing works. If I convert it to a polygon first, define projection works but the reference on the map is still completely wrong. I think these problems occur because of the "uncommon" raster format?

I also think that the projection from the screenshot is not equal to the one I posted up here?

My goal is to project it in the end to "British National Grid" as all my layers I work with have this projection.

I also tried it on another computer with ArcGIs 10.2 and the same problem occured.

I am using ArcGIS 10.2.2 for Desktop.
