That shows that the following line in grub.cfg is your problem.

Note that this is not the same thing as the root= arguments
appended to the 'linux' lines : those tell the kernel specified in
that line where it should find it's '/'. This one is to tell grub
where to look for kernels. Try setting it back to hd0,msdos1.

And just to be clear, if grub's root is hd0,msdos1 then all of your
kernels need to be in the *lubuntu* /boot directory. Before you
fixed up grub.cfg again, it could not find any kernel - that suggests
you had correctly moved the lfs kernel to lubuntu's /boot, or at
least not put it in LFS's /boot, so adding that stanza for LFS will
hopefully be enough for grub to find it.
Then, you will get to find out if your kernel's .config is adequate
for *your* hardware.
