Steps on how to break into a physical machine after root is inaccessible

New page

Sometimes we accidentally put in the wrong root password when creating a host or we accidentally change it to something we didn't mean to. That's no problem as long as you have physical access to the machine.

===Steps to Reset root Password===
1) Restart the computer
2) During kernel selection at boot, press 'e' to edit the kernel line
3) At the end of the kernel line, type
init=/bin/bash
4) Save that to the kernel line and then press 'b' to boot
5) Enter 'su' to become root.
6) Type command:
mount -o remount,rw /
7) Change root password with command passwd.
8) After password successfully changed, remount filesystem as read-only:
mount -o remount,ro /
9) Press ctrl + alt + del to restart computer. Boot normally and root password should be reset
