Sometimes it is necessary to get root access into the Ubuntu system. I was facing the issue when try to reset forgotten root password in Ubuntu 14.04 using recovery mode (Drop to root shell prompt). After done a few testing and do a research, i have found the working solution for it.
Steps to Reset Forgotten Root Password in Ubuntu 14.04
Give root password for maintenance (or type Control-D to continue)
1. First, make sure to choose the regular or default boot kernel that you always use, then press ‘e’.
2. Hit the down arrow key over to the “linux” option.
3. Remove the “ro” part with the backspace key, and then the following onto the end:
rw init=/bin/bash
Press Ctrl-X or F10 to boot.
4. Your system should able to boot up very quickly to a command prompt.
5. Use the following command to reset your password:
passwd
Once password has been set successfully, run sync command to write out data to the disk before rebooting.
sync reboot -f
Thats all. Now you should be able to login without any issues.

I have went through every step just as u had said but I get a /bin/bash: quiet: no such file or directory. …….. and 3.508683) kernel panIc- not syncing: attempted to kill init exitcode= 0x00007f00 what is wrong?
yep i got that though i have not fixed it
i think it is a good idear to type like this rw, init =/bin/bash
dont forget the comer( , ) after the rw, and the space before the =
dont delete the intrid line
Very useful and easy approach to recover the credentials..
Thank you..
sync
rebooting -f #wrong line…
It must be reboot -f
got as far as root@none when entering password
said authentication manipulation not changed 🙁
i did ant even set a dam root password so something is up
