[SOLVED] i cant boot into new LFS installation (lfs 7.5)

To be on the safe side not knowing where it went wrong I would start again.
If you want to make an entry in fstab thats ok just remove it after build.

Always check LFS is set "echo $LFS" even as root user and lfs user.

When you get to Chapter 6 if you reboot do check sda? mounted and DO 6.2.2 and 6.4
Think that covers it, unless Teufel as any other advice

lost+found sources tools

all my work is in /mnt/lfs directory, but /mnt/lfs isn't connected to /dev/sda5.

if /mnt/lfs directory has no any partition attached (not mentioned in "mount" command output) but still has your system LFS installed there it seems you installed your system not at sda5, but at /mnt/lfs that belongs another filesystem.
However it dosn't explain why grub found your kernel at sda5.

Did you try to find lfs kernel location from grub shell?

yes, you are right!

maybe it didn't found.
i just have a new entry in the grub menu.
maybe it just that: menu entry, and nothing else :-)

i tried before to search in grub command line, like that:
search -f /boot/vmlinuz-3.13.3-lfs-7.5

it didn't find anything because this file(as i know now) is in /mnt/lfs/boot
and as you(and me) understand now, it's just a folder in my archlinux system :-)

remove it after i finished everything and i'm just before the restart to my new LFS system?

i did it.
even now echo $LFS give me /mnt/lfs, if i change to user lfs :-)

spiky0011 · 11-30-2014, 01:53 PM

yea remove from fstab when lfs boots, that shows that lfs is set "dosn't hurt to check"
as Teufel mentioned what is in /mnt/lfs without sda5 mounted?

Obviously you forgot to mount sda5 before starting installation.
Seems you have to re-install it.
Though things might be moved from /mnt/lfs to sda5, but I think it would be very tricky to get it configured properly.

Though, I would try to boot into LFS by editing grub menu entry to get it pointed to root as
root=<arch partition>/mnt/lfs/boot/vmlinuz.......
Just out of curiosity

i tried but i get the same error which is strange because i know for sure that my /mnt/lfs is on sda3.
i did it like that:
linux /mnt/lfs/boot/vmlinuz-3.13.3-lfs-7.5 root=/dev/sda3 ro

Another final option if the files are there, A long shot mount sda5 cp -r all the directories to sda5 If that fails clean up and start again

you are the man, my friend!
it is working.
i can boot into LFS!!!
it's ugly like hell is, but i'm very (very!) happy!
thank you very much!

i mount /dev/sda5 to /mnt/pashosh
then i: cp -rf /mnt/lfs/* /mnt/pashosh

waiting... ...

after finished i: umount /mnt/pashosh

and then: mount -v -t ext4 /dev/sda5 /mnt/lfs

i remove the entry i made manually before, from the file '/etc/grub.d/40_custom' (don't need it, because grub-mkconfig will do the trick).
save this file
now when i do: grub-mkconfig -o /boot/grub/grub.cfg

it also find! my LFS!!! (besides the other already recognized OSes (arch and windows)).

reboot

now, when i press the LFS menu i get into the system.

great great greeat!
again, thank you very much!

Can you post your fstab for both systems &

Isn't sda5 seen as hd0,4?

sda1 is windows 7
sda2 is another ntfs partition.
sda3 is where my archlinux exist.
sda5 is my LFS :-)

my /etc/fstab in archlinux is:

Code:

# <file system>	<dir>	<type>	<options>	<dump>	<pass>

  /dev/sda3     /         	ext4      	rw,relatime,data=ordered	0 1

  /dev/sda6     none            swap            defaults                        0 0

ignore the 'openwrt' (i need to change it to something else, more normal :-))

and in LFS:

Code:

# file system  mount-point  type     options             dump  fsck
#                                                              order

/dev/sda5     /            ext4    defaults            1     1
/dev/sda6     swap         swap     pri=1               0     0
