Set a default operating system, adjust the menu timeout, or schedule a one-time boot without making it your new default.
Inspect UEFI entries and arrange the boot order from a clear desktop interface. Review your draft before you apply it.
Inspect backups and restore supported settings. System changes use the installed administrator helper and automatic backups.
