  2. Change the value for the parameter GRUB_TIMEOUT in the /etc/default/grub file.
  3. (Optional) Generate a new password by running the following command:
  4. (Optional) Replace the existing GRUB password in the /etc/grub.d/40_custom file.
    The default password is VMware1.
  5. Update the GRUB configuration.
