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
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 ?
das eine Mal als Tragödie, das andere Mal als Farce
