In the SAS Topology screen in <strong>CTRL+C<\/strong>, a user can scroll down to either select the desired Physical Disk or Virtual Disk and assign that device as their Preferred Boot Device by pressing ALT+B. The Preferred Boot Device will then be marked as &#8220;Boot&#8221; under Device Information.

It could simply be that there is a different style of sticker on the different parts.
