This command reboots the system directly into the GRUB boot menu.
From there, boot parameters can be temporarily edited or another entry selected.

After executing the command, the terminal is cleared and the following message is displayed:

    Do you want to reboot NOW? Please make sure to safe all work.
    Type 'y'/'yes' to continue or 'n'/'no' to abort

Upon confirmation, the system will automatically reboot.
During the next boot, the GRUB menu will appear and remain open indefinitely.
