I think the root of your problem is that you have no previous good .config for _this_ laptop. As we always say, both the filesystems and device drivers that are required to boot need to be built in to the kernel. But something about your report is odd - you say it lists the sda partitions (and I assume that is the correct drive), and I also assume you aren't using a different filesystem for '/' on this machine. Did you perhaps specify root=/dev/hdXN instead of /dev/sdaN in grub.cfg ? ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
