[SOLVED] Boot hangs after creating a new /boot partition and upgrading to Intrepid

**bela83** · November 1st, 2008

Hi everybody !

While upgrading to Intrepid, I did something I had long wanted to : I created a new partition (96 Mb ext2) for my /boot. I copy-pasted my old boot folder on the new partition, I upgraded and now I can't boot into my new system. The boot process hangs at 4 or 5 seconds, and I have no info. Please could you help me, I'm no newbie, I can boot on my computer using an old Knoppix Live CD, and I'm not afraid of the command-line

OK, how about first posting:

Code:

sudo fdisk -lu

For your main Ubuntu partition sdX (replace that with the actual partition):

Code:

sudo mkdir /mnt/Ubuntu
sudo mount /dev/sdX /mnt/Ubuntu
cat /mnt/Ubuntu/boot/grub/menu.lst

Also, for your /boot partition sdY:

Code:

sudo mkdir /mnt/Boot
sudo mount /dev/sdY /mnt/Boot
ls -lR /mnt/Boot

And lastly please post:

Code:

sudo blkid -c /dev/null
cat /mnt/Ubuntu/etc/fstab

And we can work from there.

Thanks caljohnsmith for considering helping me !
I'm busy right now but I'll be back in 3 hours with the output of the commands...
Thanks again...

OK, since you moved your /boot directory over to the sda1 /boot partition, you should move /boot in your main Ubuntu sda2 partition to a backup directory so you can mount the sda1 partition on /boot:

Code:

sudo mount /dev/sda2 /mnt
sudo mv /mnt/boot /mnt/boot.backup
sudo mkdir /mnt/boot
sudo mount /dev/sda1 /mnt/boot
gksudo gedit /mnt/boot/grub/menu.lst

in your menu.lst, first change the line that has "# groot=(hd0,2)" to be:

Code:

# groot=(hd0,0)

Save and quit gedit, next do:

Code:

sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo chroot /mnt /bin/bash
update-grub
exit

Next check your menu.lst and see if you have the following Ubuntu entry:

Code:

title           Ubuntu, kernel 2.6.27-7-generic
root            (hd0,0)
kernel          /vmlinuz-2.6.27-7-generic root=UUID=b412bf8d-bd1b-4f72-84d2-236d414c0c0e ro quiet splash
initrd          /initrd.img-2.6.27-7-generic
quiet

It might be that the update-grub script will use UUIDs instead of (hd0,0), so if it does, it should look like:

Code:

title           Ubuntu, kernel 2.6.27-7-generic
uuid            8999fa39-30c2-497d-8018-05f8f6e1fed8
kernel          /vmlinuz-2.6.27-7-generic root=UUID=b412bf8d-bd1b-4f72-84d2-236d414c0c0e ro quiet splash
initrd          /initrd.img-2.6.27-7-generic
quiet

Note there should be no /boot in front of the kernel/initrd lines, so make sure it's not:

Code:

title           Ubuntu, kernel 2.6.27-7-generic
root            (hd0,0)
kernel          /boot/vmlinuz-2.6.27-7-generic root=UUID=b412bf8d-bd1b-4f72-84d2-236d414c0c0e ro quiet splash
initrd          /boot/initrd.img-2.6.27-7-generic
quiet

Next reinstall Grub to the MBR and have it point to your new boot partition:

Code:

sudo grub
grub> root (hd0,0)
grub> setup (hd0)
grub> quit

And I think you should be all set. Reboot, and let me know if you run into any problems. Otherwise let me know how it goes.

**bela83** · November 1st, 2008

Thanks ! I don't understand though your first advice, I already moved the old folder to /boot_old. May I skip this point ?

And also for the second point this is already (hd0,0). I go on...

**bela83** · November 1st, 2008

Bad news... Still not booting. So I think it's not a Grub problem... In fact, the boot sequence hangs after prompting

Code:

Begin: Running /scripts/local-premount...
Begin: Waiting for resume device...

**caljohnsmith** · November 1st, 2008

Yes, it does sound like that may be a booting problem with Intrepid and not a Grub problem. Can you boot some of your older Hardy kernels from the grub menu? Also, if you feel like posting the menu.lst from your /boot sda1 partition, I could look it over in case we missed something.

**bela83** · November 1st, 2008

This is the point, I was playing in Synaptic and I removed some linux-2.6.24... packages (not the base but the restricted or something like that). So I played with fire and I burnt ! I have to say I have no excuse...
When I tried to boot the 2.6.24 kernel, I got to the desktop and the system freezed before I could do anything.
Anyway here's the menu.lst :

### END DEBIAN AUTOMAGIC KERNELS LIST

**caljohnsmith** · November 1st, 2008

OK, how about doing this to install another kernel:

Code:

sudo mount /dev/sda2 /mnt
sudo mount /dev/sda1 /mnt/boot
sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
sudo chroot /mnt /bin/bash
apt-get install linux-headers-2.6.24-21-generic linux-image-2.6.24-21-generic linux-restricted-modules-2.6.24-21-generic linux-ubuntu-modules-2.6.24-21-generic
update-grub
exit

Then check your menu.lst to make sure it has the new kernel listed and everything is in order:

Code:

cat /mnt/boot/grub/menu.lst

Let me know how that goes.
