The drivers have been installed. The stuff to re-install will be in the D: \Recover file system. If you download drivers from Medion, either create C: \Medion first or download to some other location - personally I would create D: \drivers and put them there, as if you reinstall the OS then I imagine everything on C: will get erased...
Blasted smiles. Of course there shouldn't be a space between : and \ above, but without it you get the red 'wibble' smiley.
