This means that grub attempted to read blocks from a partition which
were actually past the end of the partition. The simplest example of
how this would happen is if you had a 20 GiB ext4 parititon, used
fdisk to make the partition only 10 GiB, but forgot to resize the
filesystem also. So the ext4 filesystem's metadata would state that
there was a file around 15 GiB into the filesystem, even though the
partition is only 10 GiB, thus causing this read error. I don't think
that something so simple is happening here though. You either have an
invalid partition table for some reason, or grub is interpreting the
partition table incorrectly (which is more likely if you're using BSD
slices that a more standard msdos or GPT label). You're using a
relatively old version of grub, and I think I remember improvements to
grub's support for slices being improved post 1.98 so using a newer
version of grub might be worth trying. Also please post the output of
"parted -l" so we can see your exact partition layout.

I don't know what is causing this error.

It's pretty much guaranteed then that the commands you're running
manually at the grub shell are not the same as those contained in your
custom menu entry.

As mentioned by John Little, the search command overrides the "set
root=foo", so make sure that the UUID in the search line is correct
and actually unique.
