"I, uh, forgot the root password"
Let's look at recovering the root password from the boot loader. If you're using GRUB, then, as GRUB loads up, highlight the Red Hat Linux entry on the GRUB menu and then press [E] to edit the boot configuration. Locate the following line, something that looks like this:
kernel /boot/vmlinuz-2.4.20-0.70 root=LABEL=/hdc=ide-scsi
Type the number '1' at the end. Doing so boots the PC into run level 1-single user mode, where you're automatically logged in as root. This done, type 'passwd' at the prompt. You can enter a new password here.

Question.
I am doing a project on Linux platform. Someone has added the GRUB password to the computer on which I am working and has also changed the root password. I can crack the root password, if there is no Grub password, from the initial screen (i.e. from the init 1); but with the GRUB password. While reading LinuxForYou, I saw your section and thought you may be able to help.
Answer.
To break the GRUB start-up password, follow the steps given below:
1. Boot the system with the first Linux CD. At the boot prompt, type linux rescue to switch to rescue mode. In rescue mode you will be asked if similar steps should be followed, which need to be followed in the installation. Once you get the # prompt, type the following command:
# chmod /mnt/sysImage
2. Edit the grub.conf file and remove the passwd line from the file. Save the file and exit.
3. Once your machine reboots, you will be able to start your Linux OS in the usual manner.
