disk `hd0,4' not found

LFS 11.0

Cannot boot into either LFS or Debian.
My LFS root partition is SDA4.
Earlier I got these other error messages:

Code:

`/boot/vmlinuz-5.13.12-lfs-11.0' not found

and

Code:

`x86_64-efi/linux.mod' not found

Not having much luck with the Rescue Disk.
Thank you for your help!

This is what I got:

error: file `/boot/grub/grub.cfg' not found

Code:

grub> fdisk -l

error: can't find command `fdisk'.

The commands are from the host system, not from the grub prompt.
From the grub prompt post the output of
set
ls

I cannot access the host system (Debian bullseye).
I'm having to type what I see on the screen into a different computer.
Here are a few of the results from "set":

Code:

cmdpath=(hd0,msdos1)/EFI/BOOT

grub_platform=efi

prefix=(hd0,msdos1)/grub/grub

root=hd0,msdos1

That root value could be wrong, as my LFS is sda4.

the sdb4 maybe sda4 or sdc4
for debian try /boot/vmlinuz /boot/initrd.img or /vmlinuz /initrd.img with whatever drive it is on.

Your list all your drives/partitions

Code:

ls (hd1,4)/

ls (hd1,3)/

ls (hd0,1)/

and so forth to find the location of kernels.
