It sounds unpleasantly familiar. For me the network cable has not proven
the magic trick. Have you installed fglrx, the proprietary graphics
driver? My problems started with that. As unlikely as this sounds, I
have had consistent success booting into W7 first. Right now I am at the
end of installing 11.04 with fglrx. I'll know very soon if this helped.
