/boot showing only grub folder and other files are not exist

Hi..All,
Today in our office one of the PC(Ubuntu11.04) was not booting up and showing continuous blinking. Then I booted through Ubuntu11.04 Rescue CD and found I was able mount all partitions apart from /boot.
Here is the /boot and / partition details

Code:

/dev/sda1 is /boot  100 MB

/dev/sda2 is /  50 GB

Then I ran

Code:

fsck /dev/sda1

command to check the file system for /boot partition. It was prompting many times(nearly or more than 50 times) as whether yes or no to fix, then I killed the process and used

Code:

fsck -y /dev/sda1

It took a while and stopped itself. Then I mounted the /boot partition and found nothing was inside the /boot partition!!?,
Does this fsck command wiped out everything?
I unmounted the /boot partition and installed the grub using below steps

Code:

mount /dev/sda2 /mnt

mount /dev/sda1 /mnt/boot

grub-install --root-directory=/mnt /dev/sda

grub got installed successfully, Then I ran the below commands

Code:

mount --bind /proc /mnt/proc

mount --bind /dev /mnt/dev

mount --bind /sys /mnt/sys

chroot /mnt/ update-grub

Found it updated successfully. Then I unmounted all partitions and rebooted. But it is not booting and giving grub prompt

Code:

grub>

Then I again booted through rescue CD, and mouted /boot and / partitions as above and found apart from "grub" folder, the other files(abi-3.0.0-12-generic, memtest86+.bin, config-3.0.0-12-generic, memtest86+_multiboot.bin, System.map-3.0.0-12-generic, initrd.img-3.0.0-12-generic, vmcoreinfo-3.0.0-12-generic, vmlinuz-3.0.0-12-generic which are exist in the other machine) are not exist in the /boot partition. So please help me what can be done to recover other files and to make the system to boot up again.

You should download kernel images for your distro from their site and install them.

the simple way:

Code:

mount /dev/sda2 /mnt

mount /dev/sda1 /mnt/boot

mount --bind /proc /mnt/proc

mount --bind /dev /mnt/dev

mount --bind /sys /mnt/sys

chroot /mnt

apt-get install linux-image-XXXX

update-grub

Should do the trick.

Don't forget to replace XXXX with kernel version or simply use aptitude

EDIT:
The {sometimes faster} way:
The other way(after chrooting):
They are already somewhere in pool directory in the rescue disk.
Copy them to /var/apt/cache/archive
And

Code:

mount /dev/sda2 /mnt

mount /dev/sda1 /mnt/boot

mkdir /mnt/cd

mount --bind /media/cdrom /mnt/cd

mount --bind /proc /mnt/proc

mount --bind /dev /mnt/dev

mount --bind /sys /mnt/sys

chroot /mnt

cp -r /cd/XXXX/pool/l/XXXX /var/cache/apt/archive

dpkg -i -GE /var/cache/apt/archive/linux-image*.deb

update-grub

Thank you very much FastCode

Code:

mount /dev/sda2 /mnt

mount /dev/sda1 /mnt/boot

mount --bind /proc /mnt/proc

mount --bind /dev /mnt/dev

mount --bind /sys /mnt/sys

chroot /mnt

Could you please guide me that how can I search the linux-image version from the internet for the below command

Code:

apt-get install linux-image-XXXX

Since I don't know the linux-image version, I installed aptitude package and ran the below commands

Code:

aptitude install linux-image

update-grub

Good Fix!, Now I got the grub menu and able to boot both of the O/S. Thanks for your kind assistance.
