I'm having trouble installing W7 on my Dell Latitude D630 due to a 'cant find install.wim' error. The DVD is a pukka Dell but my drive and two I've borrowed from colleagues just struggle with it. I can however boot from the dvd and install ok on a very old desktop pc with a x8 dvd rom. Short of using an ide/usb coverter to use the old drive on the laptop I can't think of a work around. Is there anything I should know? Thanks.
