hi i have bought this motherboard https://www.asus.com/Motherboards/PRIME-B550-PLUS/ but it is only booting in uefi ( in need to customize installer and allow uefi boot) but i dont wanna boot uefi does B550 Only support uefi boot or is it just a setting in windows? and if i try to plug in unraid usb key without uefi boot allowed it just goes in to bios and doesnt boot from the usb key
