Question LFS system can not boot on my laptop

hello everyone !
I am very interesting linux from scratch.and on virtualbox I have build an LFS system and boot it successfully.
These days i want to compile the LFS system on an old 32bit laptop of mine.but i cant boot it.
The error is:
Code:
error:file '/boot/vmlinuz-4.12.7-lfs-8.1' not found
2.the disc and mount are:
Code:
root:/# lsblk
NAME   MAJ:MIN RM    SIZE RO TYPE MOUNTPOINT
loop0    7:0    0 1020.1M  1 loop 
sda      8:0    0  465.8G  0 disk 
|-sda1   8:1    0    200M  0 part /boot

`-sdb4   8:20   1    7.2G  0 part 
sr0     11:0    1   1024M  0 rom
3.the /boot files are
Code:
root:/# ls /boot/

grub	       lost+found	  vmlinuz-4.12.7-lfs-8.1
4. the grub.cfg is
Code:
root:~# cat /boot/grub/grub.cfg 
# Begin /boot/grub/grub.cfg
set default=0
set timeout=3

insmod ext2
set root=(hd0,1)

menuentry "GNU/Linux, Linux 4.12.7-lfs-8.1" {
linux   /boot/vmlinuz-4.12.7-lfs-8.1 root=/dev/sda3 ro
initrd  /boot/initrd.img-4.12.7
}
5.the fstab is
Code:
root:~# cat /etc/fstab

try the linux line without /boot
linux /vmlinuz-4.12.7-lfs-8.1 root=/dev/sda3 ro

My 2 cents.

Recently (2018-02-05) i started playing with lfs, went for the devel-book of lfs, that first build crashed because the partition i used ran out of space, restarted with the new devel-book and got to a successful end.
Regarding the grub i had (and partitial still have a problem) and gave it my own interpretation. grub provide a grub-mkconfig (hint: grub-mkconfig -o /your/path/grub.out) util i ran on the lfs. That that file created in /your/path/ i edit down to the menu-listing structure like following:
Code:
menuentry 'Linux From Scratch' --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-6c5d12d6-73e8-4a76-a4f6-8cfb53d8360e' {

}
This piece can be inserted in several ways into the real grub.cfg. Mine was to going to disable grub rebuild on every other disrtibution i currently run and put the code right into the /boot/grub/grub.cfg of the actual boot-map responsible for starting grub. in mine example pasted above into excisting grub.cfg at line 134. In your case the produced file of grub-mkconfig could work inmidiate but took the trouble of displaying mine situation which is almost the same except you're using a seperate boot partition (you can consider to put the /boot temporary at the root partition and test that before seperate it again)
little last remark: lfs don't need an initrd to boot properly ( only on some rare conditions )

If your final goal is invoking your Linux, you can simply use super grub2 disk, https://www.supergrubdisk.org/super-grub2-disk/

Thanks,

thank you for eveyone!
in fact . I have solved it by this.when i reboot the systems and use E key to the grub terminal and use it like Linux terminal .
for example . set root=(hd0,msdos1) .just push the button "Tab".When i find the vmlinuz* and ctrl+x to boot it .its successful.

so the grub line should be as I said
linux /vmlinuz-xxx
The reason is that there is no boot dir in sda1

Of course! That's mainly my reason never to put out the /boot on a separate partition and leaving it
inside the distribution. It is more an horror when you start playing with multiple distros. When mount a separate part to /boot it's the root and making a /boot in there would result in /boot/boot
May be it can be tricked by making a link from /boot to / but i wouldn't go that way.

In my own situation i solved the trouble of updating the grub.cfg on several distros by moving the 'real' acting grub to the lfs. lfs never will touch the grub.cfg and i moved my theme of grub inside there and changed the root-pointers from hd0,msdos14 to hd0,msdos13 where lfs is running. Any other distro can do whatever they like with their own not used grub.cfg

Congrats on topic-starter for making it work.
