Can't find Windows in BIOS and Boot

After downloading Manjaro (HDD), I can’t see Windows Boot Manager (SSD) in boot. I tried spamming F12 yet all I see is Manjaro. What should I do?

Check your machines manual, perhaps it’s using another key than f12. Sometimes f2 or f8 works.

As you’re using an UEFI installation you can also try to boot up Manajaro and reboot into the firmware:

$ systemctl reboot --firmware-setup

I tried F2 it brought me to BIOS yet the only OS i can see is Manjaro. I will update you as to what F8 do.

Could it be that Windoze is installed in BIOS mode? I can’t see a suitable ESP on /dev/sda.

In this case you could try to enable Legacy/CSM Boot Support in your firmware, then you should be able to boot the Windoze disk from your firmware.

I tried F2 and the only options in boot was

(1) null string (it’s enclosed inside <> but it disappears when I do that)
(2) Manjaro

How can I do that? Do I need to burn the ISO image again? How?

Legacy/CSM Boot Support is often an option you can enable/disable directly in your firmware/BIOS.
