Because it's not in Windblows.

You're missing the BIOS, there's lots of stuff in there you really shouldn't mess with, and a few you really should. Pressing F8 in that split second between the boot screen and the Windblows start screen works with this mobo, with Dell I haven't a clue. Then you have to ask the right questions to get the right answers, maybe someone here or someone out there on the cloud knows Dell.
I tried to tell you about that gauze filter in front of the intake fan that cools the drives in the above picture and all other unused fan mounts sealed with tape so air goes in the front and out the back twice, and got THIS mess twice. That's clue enough, I'm not about having it screw up thrice. No pictures, no screenshots, no more cockups.
