Mini HOWTO: Recovering from a forgotten GRUB bootloader password

Here's how to recover from a forgotten GRUB bootloader password:

Edit /boot/grub/grub.conf and comment out (#) or delete the password entry. Then, GRUB will no longer require a password to edit the boot lines.

If you want to assign a new password perform these steps:

**enter `grub` as root.

**Run md5crypt:

Code:

grub>md5crypt

**Enter a new password.
The password will then be output to the terminal in MD5 format.
Then you can cut and paste (or highlight and middle-click) this encrypted password into your password statement.

To be more specific, when you create the MD5 password hash with md5crypt and want to set it in the grub.conf, the correct format is:

Code:

password --md5 md5_hash
