Changing Ubuntu Root Password

Boot from the Ubuntu Install CD.

when the first installation screen appears press CTRL+F2 to bring up another terminal and press Enter to activate it.

Create a mount point by entering the following:

mkdir /mnt

If you don't know the partition that you want to mount then enter the command:

cat /proc/partitions

For my example the root file system is installed on /dev/sda3

Now mount your root file system to the new mount point by entering the command:

mount /dev/sda3 /mnt

Now we need to change the root file system to the newly mounted one and this is done by entering the command:

chroot /mnt

Once you are at the command prompt you can now enter the passwd command to change the root password.
