Recovering the root password from the boot loader (GRUB)

When GRUB loads up, select the Red Hat Linux entry on the GRUB menu and then press "e" to edit the boot configuration.

Locate a line like this:

kernel /boot/ root=LABEL=/hdc

- type the number '1' at the end.

Doing so boots the computer into run level 1- single user mode you will automatically be logged in as root.

Type 'passwd' at the prompt, now you can enter a new password here.
