Ubuntu Single User Mode without root password for maintenance
Hello Friends,
I came across problem , while resetting ubuntu password , Generally when we reset password for RHEL 5 OS , we enter into single user mode through grub by editing Kernel line with Single or 1 , and simply you will boot into single user mode.
But with Ubuntu it was a kinda different.
1.Reboot your machine; press 'Esc' to get to the GRUB menu; select your image; press 'e' to edit; select the Kernel line.
2.Press 'e' to edit the kernel line. Edit the line to get rid of quiet and splash; change 'ro' to 'rw'; and add 'init=/bin/bash'. The line should look something like this:
kernel /vmlinuz-2.6.15-27-386 root=/dev/mapper/Ubuntu-root rw init=/bin/bash3.Press 'enter' then 'b' to boot with these new settings.
Then you can fire up passwd command to reset root password.

It Works!
