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!

fdisk -l

Thanks for the help!
This is what I got:

Code:

grub> cat /boot/grub/grub.cfg
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.

what is the ouput of

Code:

grub>ls
grub>ls /grub
grub>ls /grub/grub

bayou self · 12-14-2021, 06:01 PM

Code:

grub> ls
(hd0) (hd0,msdos1) (hd1) (hd2)

Code:

grub> ls /grub
grub/

Code:

grub> ls /grub/grub
x86_64-efi/ locale/ fonts/ grubenv

insert the following commands and post output of ls.

Code:

insmod part_gpt
ls

bayou self · 12-14-2021, 06:07 PM

Code:

grub> ls
(hd0) (hd0,msdos1) (hd1) (hd1,gpt4) (hd1,gpt3) (hd1,gpt2) (hd1,gpt1) (hd2)

colorpurple21859 · 12-14-2021, 06:11 PM

Code:

insmod part_gpt
linux (hd1,4)/boot/vmlinuz-5.13.12-lfs-11.0 root=/dev/sdb4
boot

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

I got

Code:

error: file `/boot/vmlinuz-5.13.12-lfs-11.0' not found
grub> boot
error: you need to load the kernel first.

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.
