Ubuntu – reset root password

If you forgot your root password or to login to Ubuntu (for recovery) without the root password, follow these simple steps:

  • While the computer boots, press ‘Esc’ as soon as the Grub loads to go into the menu.
  • Press ‘e’ to edit the boot menu
  • Select the kernel line and again press ‘e’
  • remove the words ‘ro’, ‘quite’ and ‘splash’
  • put these words at the end – ‘rw init=/bin/bash’
  • press enter to accept
  • then press ‘b’ to boot into linux

Now you will get to the root shell in a while. Mount all partitions using ‘mount -a’ command (somtimes some partitions are not mounted). Then use ‘passwd’ command to set a new password. Or, you can perform maintenance task right there.
