Booting into single user mode from GRUB
Follow these steps to reset the password when using GRUB:
- Reboot the system, and when you are at the selection prompt (See Fig. 2 below), highlight the line for Linux and press
'e'. You may only have 2 seconds to do this, so be quick.
- This will take you to another screen where you should select the entry that begins with
' single'to the end of that line (without the quotes). Make sure that there is a space between what's there and
'single'. If your system requires you to enter your root password to log into single-user mode, then append init=/bin/bash after 'single'. Hit
'Enter'to save the changes.
'b'to boot into Single User Mode.
- Once the system finishes booting, you will be logged in as root. Use passwd and choose a new password for root.
- Type reboot to reboot the system, and you can login with the new password you just selected.
