Following is the procedure to reset root password if you are
using GRUB as a boot loader:
1. Select the kernel
2. Press the e key to edit the entry
3. Select second line (the line starting with the word
kernel)
4. Press the e key to edit kernel entry so that you can
append single user mode
5. Append the letter S (or word Single) to the end of the
(kernel) line
6. Press ENTER key
7. Now press the b key to boot the Linux kernel into
single user mode
8. At prompt type passwd command to reset password:
You need to mount at least / and other partitions:
# mount -t proc proc /proc
# mount -o remount,rw /
Change the root password, enter:
# passwd
Finally reboot system:
# sync
# reboot
