On my first try with LFS, I did version 8.4 systemd on an SSD with all

It boots just fine.
I just did version 9.0 systemd on another SSD, all in one partition also.
However, in Chapter 8.4.3 Setting Up the Configuration, I ran into an
issue with this different SSD
(grub-install /dev/sda)

Since I would not be booting with UEFI, I picked the "|--target i386-pc."|

|Installing for i386-pc platform.
grub-install: warning: this GPT partition label contains no BIOS Boot

grub-install: warning: Embedding is not possible. GRUB can only be
installed in this setup by using blocklists. However, blocklists are
UNRELIABLE and their use is discouraged..
grub-install: error: will not proceed with blocklists.|

|Using gparted, I reduced the size of the single partition, and moved
it away from the start of the drive. I then made an ext2 partition,
and marked it with a flag of bios_grub as what I read I should do.
However, now it is being labeled as sdX2, if that makes any difference.

EOF

|All I am getting on screen is:|

Just an update, something I left out and tried to do (no, not resolved)
I did not create or copy the grub.cfg file over to the boot partition
I just created what I had (working from version 8.4 booting from sda1)
then copied it over to the boot partition.
Turns out that was incorrect as it gave me the same result when booted.
More closely reading 8.4.4. Creating the GRUB Configuration File, I see
I needed to make some changes from the "Note" box.
So here is what I got in grub/grub.cfg:
*********
# Begin /boot/grub/grub.cfg
set default=0
set timeout=5
insmod ext2
set root=(hd0,2)
menuentry "GNU/Linux, |Linux 5.2.8-lfs-9.0-systemd|" {
linux /|vmlinuz-5.2.8-lfs-9.0-systemd |root=/dev/sda2 ro
}
********
Remember, I have the boot partition as an ext2 with "bios_grub" flag
set, and in this case the machine is boots on, makes the partition sda2
(The example in the book shows an identical setup in grub.cfg).
Seems not even those changes worked out and still getting that "GRUB"
message on boot with the blinking cursor next to it.
