Ubuntu 10.04 Installation – Dell 15R

October 18, 2010

The new Dell 15R wipes out your GRUB2 when you boot into Windows after the installation of Ubuntu 10.04. This issue can be solved by uninstalling Dell Data Safe in Windows before the installation of GNU/Linux OS. But, if you really want to keep the Dell Data Safe installed, the solution would be to  downgrade GRUB2 to GRUB1.

Step 1: In case you already wiped out MBR, boot using a live USB/CD and reinstall GRUB2. If you have not booted onto Windows after Ubuntu installation, please goto step 2.

sudo -i
mount /dev/sdax /mnt      #x partition where / and y partition where /boot is installed
mount /dev/sday /mnt/boot #skip this one if not have a separate /boot partition
grub-install --root-directory=/mnt/ /dev/sda

Step 2: Downgrading to GRUB1
Backup GRUB2 files.

sudo cp /etc/default/grub /etc/default/grub.old
sudo cp -R /etc/grub.d /etc/grub.d.old
sudo cp -R /boot/grub /boot/grub.old

Then, remove GRUB2.

sudo apt-get purge grub2 grub-pc

Install GRUB 0.97

sudo apt-get install grub

Next, we need to generate the GRUB1 files using the following commands.

sudo update-grub
sudo grub-install /dev/sdX

Choose X as the partition where /boot is installed. We need to also ensure that synaptic does not update this GRUB automatically to GRUB2.

echo "grub hold" | sudo dpkg --set-selections

Now reboot and enjoy the freedom.

    There is an even easier way to solve this problem: The software that wipes out GRUB is Dell Data Safe (backup software), it can be uninstalled to stop the problem from recurring.

      That’s really informative. Dint know that it was done by Dell Data Safe.

      By the way, as you know, many of the windows users does not like to play around with their default installation. I feel so this one can serve as a solution in such cases.

      • Yeah that’s right, but doing downgrade to Grub 1.0 is too tedious a process compared to uninstalling a useless software.

        BTW the problem is not only with Dell 15R but will all systems Dell is shipping these days. They have this software installed.

        I have updated my blog providing the primary solution as uninstalling Dell Data Safe and secondary solution as downgrading the GRUB. 🙂

  2. Techunit here from… I have a Dell Studio 1737 and I haven’t had a problem dualbooting my computer with windows and Ubuntu, but I am dualbooting and I’m not installing Ubuntu as a primary OS. I doubt its a problem with Datasafe though. Datasafe has no influence with the MBR so I don’t know why it would cause a problem like this.
