How to reset the root password

Question

Accepted Answer

To reset the root password, you can use the single-user mode or a bootable Linux distribution.

Boot into single-user mode by interrupting the boot process and appending 'init=/bin/bash' to the kernel command line.
Remount the root filesystem as read-write using the 'mount -o remount,rw /' command.
Change the root password using the 'passwd' command.
Alternatively, boot from a bootable Linux distribution like a Live CD or USB and mount the root partition to reset the password.
