Step 1 ) Boot the system and select the normal boot menu from the list. Once selected, in the "Boot Options" box type
"init=/bin/bash" if you are using GRUB Boot loader
"linux init=/bin/bash" if you are using LILO Boot Loader
This will give you access to the bash without asking for the password.
Step2 ) Mount your filesystem using the following command
# mount
Step 3) Make the file system read write if its not already using the following command
# mount -o remount,rw /
Step 4) If you are lucky enough you can use the passwd command and change the password if it doesnot happen follow the steps mentioned next
Step 5) Edit the passwd and shadow files as follows
# vi /etc/passwd
Scroll down to the "root" line in the passwd file look for root line (something like):
root:x:0:0:root:/root:/bin/bash
Delete the "x" after "root:" leave the colons! Note: After the modification above line should look like this: root::0:0:root:/root:/bin/bash
Save file and exit. Remember [:wq]
# vi /etc/shadow
Change (something like) this -->
root:$1$42aXWP89$zcVaoeRnNVCKu4mOgJ6zt.:14289::::::
to --> root::::
Note four colons left!
Save the file and exit. Remember [:wq]
use :wq! if :wq doesnot saves it for you
Step 6) Reboot, login as a normal user change the user to root using su then than change the password using passwd
