2. Bind mount the
/proc special mount points into your
mount --bind /dev /mnt/dev mount --bind /sys /mnt/sys mount --bind /proc /mnt/proc
chroot into your installation:
chroot /mnt /bin/bash
4. Use the
passwd command to reset your root password.
5. Reboot and don't lose your password again!
Method 2 - Single User Mode
- At the Grub menu, highlight the entry for your system and press 'e' to edit.
- Highlight the 'kernel' line and press 'e' again to edit.
- Append a space and the number '1' to the end of your kernel line. This tells the kernel to boot to init level 1, or Single User Mode.
- Press enter to save, and 'b' to boot.
- The system should boot as normal, except instead of booting to a login prompt, it should drop you to a basic shell with a '#' prompt.
- You can use the passwd command from here to reset your password.
