.something directories, there are lots of them and their contents change
from time to time in ways that break things.  I've started moving them all
out of the way before an install.   I put all of the .something dirs in
~/old_dot_dirs and let the install create new ones.

it did find everything needed for the install.  I also installed the new
vmlinuz and initrd in a subdirectory of /boot but that isn't relevant here
so we can skip those differences.

Here is what was different for my config:

1. created a directory named images at the same level as the DVD.iso
2. copied install.img from /images of the iso to /images on the hard disk
    (so on the install disk there was /Fedora...DVD.iso and a directory
named /images
    with the install.img file copied from the mounted DVD.iso)

3. The last entry of the line with the repo info in grub.conf only contained
the *path* to
    the iso *not* the name of the file.  In your case, I think that this
would have worked:

kernel /vmlinuz repo=hd:/dev/sda5:/
