Inspiron 11-3168 BIOS bug?

I currently have the latest bios (2.1.1) installed and noticed there's no longer ANY way to boot Legacy ROM USB drives. When it used to work just fine, now not only do USB drives not show up in list under Legacy in F12 boot menu, but selecting to boot USB Drive shows "No Operating System Found".

Now here's the trick if I simply wait with the boot menu on screen for around 5-10 minutes then select USB Drive to boot, it boots up my live Linux distro just fine, it not always works it's hit and miss, and not all live Linux distros work, but obviously the BIOS is capable of booting it so why does this BIOS on the Inspiron 11-3168 work like this?

I tried downgrading to BIOS version 1.0.7 nothing changed, then 1.0.6 still nothing so came back up to version 2.1.1. When I first got this laptop I clearly remember booting Legacy Drives a lot and the worked perfectly and showed up in the list on the boot menu since then I updated the BIOS twice from 1.0.7 to 2.0.3 then again to 2.1.1. So one of those updates must have broken something with booting Legacy ROM drives.

The F2 Aptio AMI BIOS- Boot page shows us that the default is UEFI.



Can you boot to that page, change from UEFI to Legacy, then F10 to save. Then reboot using F12 and choose the Legacy option?

Yes of course I can and know how to change from UEFI to LEGACY, I think you misunderstood what my problem is, after re-reading my OG post I see it's a little confusing so let me try to explain again...

After changing from UEFI to LEGACY in BIOS then F12 to boot menu and attempting to boot "USB DEVICE" it flashes screen few times then says "No Operating System Found" so it does NOT work when it clearly use to just fine.

Now if I go back into BIOS and DISABLE "USB Emuration" save changes reboot, Immediately F2 to go into BIOS again and ENABLE "USB Emulation" save, reboot then F12 to enter boot menu and attempt to boot from "USB DEVICE" it works and boots up my Linux Live screen...

So this is clearly a BIOS BUG thankfully I have figured out how to bypass it with the disable/enable usb emulation workaround but the thing is my laptop use to not have this problem and trying to downgrade my BIOS did nothing, so I REALLY hope DELL technicians can fix this and release an updated BIOS..
