grub stage 1.5 error 15

[idom]

Hi

I was trying to install ubuntu 9.1 and it got stuck for a long time at some stage. finally when I rebooted my laptop and tried to boot from hdd and it is giving following error

Grub loading stage 1.5
Grub loading please wait
Error 15

It was a clean install on my primary hdd. And it got stuck twice. Hence I tried to boot from hdd. I did manual partitioning.

See this link in the errors section at the end of the initial post.http://ubuntuforums.org/showthread.php?t=1195275
File Not Found (Error 15)
This error is the result of a GRUB 2 installation to /boot but a Master Boot Record ( MBR ) which still contains Grub legacy.

Hi thanks I following instructions from

https://help.ubuntu.com/community/Gr...0from%20LiveCD

( I followed 2 METHOD 2 - Copy GRUB 2 Files from the Installed Partition )
now it is going to the grub prompt.

step no 6 Refresh the GRUB 2 menu with sudo update-grub
gave following message
grub-probe: error: cannot find a device for /.

I tried to boot from the hdd now and it went to grub prompt
can you further point out what should I do?

In your case you seem to be missing the config files too, like grub was never installed fully. From that link you posted follow the Method 3 CHROOT procedure.
That can create new config files if none exist.

[idom]

As per your suggestion, I tried running the step 3. A few steps where output was not normal

update-grub
Generating grub.cfg ...
Found memtest86+ image: /boot/memtest86+.bin

root@ubuntu:/# grub-install /dev/sda

This is the contents of the device map /boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.

root@ubuntu:/#

after that I rebooted the system and it is going into memcheck instead of booting from HDD. I think now grub is completely gone.

suggestions please..

Did you mount all devices from all previous steps as per the instructions?

To summarize, you need to execute something like:

sudo -i
mount /dev/sda1 /mnt
grub-install --root-directory=/mnt/ /dev/sda
mount --bind /proc /mnt/proc
mount --bind /dev /mnt/dev
mount --bind /sys /mnt/sys
chroot /mnt update-grub
umount /mnt/sys
umount /mnt/dev
umount /mnt/proc
exit

In the second command, replace /dev/sda1 with your root partition. Do you know what your root partition is? Were you mounting it at all?

If you are not sure about root partition, execute in terminal
sudo fdisk -l

and copy the result here and I'll see which one is it. After that execute the above commands.

I am pretty sure that it is /dev/sda1

however, I am still pasting the output here

Can you please confirm that it is /dev/sda1

I had made two primary partition for linux and for /dev/sda1 I had given mount point as /

Thanks for the help.

And I think yes, i followed all the steps.

Thanks again for all the help.

[darkod]

From this output you can't tell for sure because sda1, sda2 and sda5 are all linux type partitions. But if you selected mount point / for /dev/sda1 then that's it.
Execute the commands with /dev/sda1 in the second and see how it goes.

[idom]

I am pasting the complete terminal output

Please advise . ( /media/Modi_* are external USB disk partitions so those can be ignored , I think ) And one more comment I have to go out for something for half an hour, however, I will be back asap.

Thanks for your patience.
