Kernel missing after partial update Ubuntu 9.10

[stefj3]

Ok, I messed up and hit "ok" for a partial upgrade. My fault entirely.

Now Grub finds no kernel to boot to, only a disk diagnostic test runs when I try to boot.

Is there a way to reload a kernel to dev/sha1 from the live cd terminal?

I'd rather not lose the data on the drive with a fresh install if I don't have to.

Thanks much!

Hi and Welcome !

Check the contents of /boot folder. Isn't there any earlier kernel version?
Did you upgrade from 9.10 to latest 10.04 or just did a regular update of 9.10?

Mount /boot partition in LiveCD and post the output of ls command here.

[stefj3]

There are no other kernel options in grub. Only memtest.

not sure of my "mount" command here...sorry.

ubuntu@ubuntu:~$ mount /boot
mount: can't find /boot in /etc/fstab or /etc/mtab

There is a boot partition listed...

ubuntu@ubuntu:~$ sudo fdisk -l

Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders

Execute this

sudo mkdir ubuntu
mount -t ext4 /dev/sda1 ubuntu
ls ubuntu/boot

Post output here.

In case mount command throws error, remove -t ext4.

Sorry for the long delay, my ISP went down for 20 hours right after my last post. Here is the result of the code above.

ubuntu@ubuntu:~$ ls ubuntu/boot
grub memtest86+.bin
ubuntu@ubuntu:~$

Kernel has been removed and there is no way to re-install it.
What is in grub folder?

[stefj3]

Grub folder contains:

Splash images folder
default
device.map
e2fs_stage1_5
fat_stage1_5
grubenv
installed-version
jfs_state1_5
menu.lst
menu.lst.backup
minix_state1_5
reiserfs_stage1_5
stage1
stage2
xfs_stage1_5

thank you for your help!

Partial upgrade has messed up everything and I don't think there is a way to fix this problem because kernel is gone.

I would suggest you to backup data using LiveCD and re-install.
