Hi
If anybody can add the steps to reset if the boot loader is password protected as well, feel free to do so.

It needs to be fleshed out, but for a password protested boot loader, you can do it as long as you can boot from a CD/DVD. Boot the install media in the rescue mode, chroot to the mounted root file system, and run passwd to change the root password. (You can probably grab most of the text from an explanation on how to re-install Grub.)
I am not sure how the rescue mode handles an encrypted file system. Will it mount one if you supply the password?

If you want to help, do test and document the method that works.

I have the steps, an old one, can someone verify if it's still applicable. Sorry I don't have a test system to try it out:
1. Using an Install CD, put into the CD drive and boot from it 2. At the "boot:" prompt type "linux single" 3. Now you need to mount the partition where your grub configuration file is stored. From the "# " prompt type "fdisk -l" and from the "Device" column the line that have an asterisk is your boot partition where grub is located 4. Mount your partition "mount /dev/sda1 /mnt" (assuming /dev/sda1 is the device that has the asterisk) 5. Afterwards do: cd /mnt/boot/grub vi grub.conf 6. Find the password line and remove it 6. Save the file then do: sync; sync cd / umount /mnt reboot

Well, I can not edit it directly, but here is the text for an un-encrypted file system. I hope to have time to create a virtual machine with an encrypted file system sometime this week.
============================================================
Boot the install CD/DVD Select "Rescue installed system" Answer the prompts for language and keyboard. Starting the network is optional and probably not needed. Let the rescue mode mount your file systems in the r/w mode. Hit enter to get the shell prompt.
sh-3.2# chroot /mnt/sysimage (Change to your disk file system.) sh-3.2# passwd (Change the root password.) sh-3.2# exit (Exit the chroot environment.) sh-3.2# exit (Exit the rescue mode.)
The system will now unmount the file systems and reboot.

If you find the steps to recover from a encrypted hard disk, let me know. IIRC, the rescue mode handles it very well. Thanks

I am sorry it took so long to get back to you. The only difference with an encrypted partition is that it asks you for the pass phrase after it asks you if you want to mount the file systems. If you have more then one encrypted partition, you have the option of checking the box indicating that it is the global pass phrase, or entering a pass phrase for each encrypted partition.
Mikkel PS - I like the updated directions.

I have added a note. Thanks for confirming.
