Grub Error 15

[bradrevolver]

Hello,

I have Windows and Linux Pardus distribution. I installed Grub. (Actually I don't remember how could i do that. I founded the way from Google)

After all of that, I decided to try Ubuntu. I installed it onto Pardus partition. But I am facing Grub 15 Error at the moment?

How can I achieve that? What can I do?

Thanks for your replies and helps..

Kind regards,

[jayd512]

Hello and Welcome!

Since you're unable to boot into Ubuntu, boot up with the Ubuntu disc and run a live session.
Open a terminal and post the output of

sudo fdisk -l

Thank you very much jayd512..

Below is the output :

ubuntu@ubuntu:~$ sudo fdisk -l

But I am facing Grub 15 Error at the moment?

Hi. A grub error 15 would be from legacy grub, not grub 2 which is what Ubuntu uses at the moment. It sounds as though either that you've installed an obsolete version of Ubuntu (9.04 or before) or that grub2 didn't install properly and you have the remnants of legacy grub in the mbr from an earlier Linux installation. Which version of Ubuntu did you install?

It would be useful to see more information than fdisk can give us. The boot info script hosted on sourceforge is perfect for this, but I can't post a direct link since I don't have the necessary number of posts yet. (A very understandable anti-spam measure, I guess.) But if you google "boot info script sourceforge" you'll find it easily enough. If you find a reference to ghulselmans and meierfra, you've found the right one. Boot up the Ubuntu live CD again, download and run the boot info script and post the contents of your RESULTS.txt file. That will give all the information needed (hopefully) to diagnose and fix your problem. By the way, the output is quite lengthy. You need to enclose it between [code] and [/code] tags.

Hi.

As coffeecat noted, see:

Boot your Ubuntu Live CD, open a terminal and enter the following command to create a mount point:

sudo mkdir /mnt/sda

Then run the following command:

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

There is also an Ubuntu Grub2 tutorial on the following page with a lot more detailed information:

https://help.ubuntu.com/community/Grub2

You might want to run sudo update-grub from a terminal after you have booted into Ubuntu, I'm not sure that is necessary?

[coffeecat]

@yancek, sorry, but I don't see how that's going to work. You haven't mounted sda6 to your created mountpoint and you need "/dev/sda" at the end of the grub-install command, not "/dev/sd".

@bradrevolver, you have grub legacy installed to your mbr and Ubuntu 11.10 installed to partition sda6 as the root partition. Rather curiously you have both grub2 and grub legacy configuration files. Since this appears to be a fresh install of 11.10 (no previous kernels), it would be interesting to know how grub legacy got there. Also, grub2 is in the boot sector of sda6 where it needs to be in the mbr.

This following should work. Boot a live Ubuntu 11.10 CD. It needs to be 11.10 and not another version. There are probable minor incompatibilities between the point versions of grub2 in the more recent Ubuntu releases. Choose "try Ubuntu" to get you to the desktop. Open a terminal.

1 - mount sda6:

sudo mount /dev/sda6 /mnt

2 - Install grub to the mbr:

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

That's it. You already have a Windows menu entry in your grub.cfg file so you *should* get a fully-working grub menu when you reboot, but if there are any problems, run "sudo update-grub" from your permanent Ubuntu installation as yancek suggests.

[yancek]

You haven't mounted sda6 to your created mountpoint and you need "/dev/sda" at the end of the grub-install command, not "/dev/sd".

Yes. Absolutely right. I left my computer for a time and forgot the mount step. The sd was a typo, happens when not checking. Thanks for correcting that.

[coffeecat]

The sd was a typo, happens when not checking.

I always blame the keybraod - er - keyboard!
