As far as I can tell it is looking at the correct partition - update-grub
does this and a manual check suggests that it is OK. /boot/boot.cfg looks
like this:
Hopefully that is /boot/grub/grub.cfg.
# Begin /boot/grub/grub.cfg
set default=0
set timeout=5
insmod ext2
set root=(hd0,2)
menuentry "GNU/Linux, Linux 3.16.2-lfs-7.6" {
linux /boot/vmlinuz-3.16.2-lfs-7.6 root=/dev/sda2 ro
}
As seen from the host system, LFS is on /dev/sda8 which is the second
partition inside the extended partition sda2
If it is on /dev/sda8 on the host, then it's on /dev/sda8 on LFS too.
What can be confusing is that other installations also write to the
grub.cfg file, but they may not know where.
Did you run 'grub-install /dev/sda' ?
If so, then other distros' version of /boot/grub/grub.cfg are not used.
Note that some distros use /boot/grub2/grub.cfg, but the question here
is "Where is the /boot directory?" I highly recommend a separate /boot
partition (100-200 MB) for all distros to share.
In any case, if you did run grub-install, then you need:
set root=(hd0,8)
menuentry "GNU/Linux, Linux 3.16.2-lfs-7.6" {
linux /boot/vmlinuz-3.16.2-lfs-7.6 root=/dev/sda8 ro
}
If you do use a separate /boot directory, say sda4, grub.cfg would
be:
set root=(hd0,4)
menuentry "GNU/Linux, Linux 3.16.2-lfs-7.6" {
linux /vmlinuz-3.16.2-lfs-7.6 root=/dev/sda8 ro
}
Note that in this case the kernel location is relative to / (the
unmounted boot partition).
