====== Ubuntu error message grub-install (hd0) failed ======
I have found the problem.

This is assuming that Ubuntu Linux is running off /dev/sda3 on the hard drive.

Run an Ubuntu liveCD and open a command prompt.  Type in sudo fdisk -l, or fdisk -l if you are using another LiveCD. In some cases, Clonezilla 1.2.0-25 does this, Clonezilla will destroy this Linux partition and it will be called W95 FAT32. This will not work. You have to do some troubleshooting. The solution I will provide below. If you want to keep the existing data in the Linux partition which would be called W95 FAT32 if it is broken, back up the data using Clonezilla and/or a Linux LiveCD before continuing.  In some cases, Clonezilla will backup the data and destroy the GRUB and/or the filesystem in the process.

1. **Make a backup of all important files using an Ubuntu LiveCD**. The partition is still readable by the LiveCD, but not GRUB.  Therefore, we will have to clear the partition.  Later, you will have a choice between using Clonezilla to restore the partition, or reinstall Ubuntu.  In case of failure, you still have a copy of the important files.

2. Reboot the computer and boot up GParted livecd. You can download GParted from [[http://gparted.sourceforge.net/]]. This is a live CD, so copy it to a CD.

3. Use GParted to delete the EXT3 filesystem then create an EXT3 filesystem for the partition that you want to use. **NOTE**: Grub will seem broken because it sees the Linux partition as a W95 FAT32 partition, but GParted sees it as an EXT3 partition. Therefore, you will have to reformat the partition.

4. Reboot and choose either a) or b)

a)If you are using Clonezilla, you can restore the partition using Clonezilla after finishing this step.  In some cases, Clonezilla will destroy the GRUB, but the backup will still be successful.  You are all done if you restored the partition using Clonezilla.  I tested this on my laptop and it worked. The filesystem was broken, but Ubuntu was still intact. I restored Ubuntu after using GParted.

b) If you did not restore the partition using Clonezilla, continue to step 5.

5. Reboot the computer and boot up the Ubuntu LiveCD.

6. Install Ubuntu, but do not format the partition. Just overwrite the contents in that partition.

7. Reboot after installation is done and all will be good.
