Regarding garuda-inxi and dual boot: I just discovered that running it on my Garuda Cinnamon machine says: "Windows dual boot: Probably (Run as root to verify)".
When running as root, it says: "Windows dual boot: No/Undetected" (and rightly so).
Therefore, I'm wondering: is "Probably" the default value here, or did it perhaps discover the presence of /sys/firmware (since Windows was installed initially)?
