Latitude 7400 - BIOS 1.13.0 - No bootable devices found
Hello,
I have just bought a Latitude 7400. It had Windows 10 installed but I am a Linux user and I only checked that Windows boots up correctly.
- As the first thing, I proceeded to updating BIOS to the latest version for Latitude 7400 which, as of today, 31-08-2021, is 1.13.0.
- I installed this BIOS version via F12 -> BIOS Flash Update. The update apparently worked fine in the sense that there were no errors reported.
- Next, I inserted a USB drive with an EFI/GPT Ubuntu 18.04 image to install this system.
- When I press F12, I can see the disk drive among "UEFI BOOT" options.
- When I go to F2 -> General -> Boot Sequence, I can also see the drive recognised.
- Also in F2 -> Secure Boot -> Secure Boot Enable is checked.
- Still in F2 -> POST Behaviour - > Fastboot is thorough.
- And again in F2 -> System Configuration -> USB Configuration -> Enable USB Boot Support is checked.
As far as I can see, the firmware is updated and configured to boot from the USB drive.
However, when I do select the USB drive to boot from through F12, I am greeted with a popup with a title of "Critical Error Message" whose contents is "No bootable devices found".
The popup is displayed on a white background with "Dell. SupportAssist | Pre-Boot System Performance Check" at the top.
When the popup displays, I can only click a Shutdown button, there is nothing else displayed.
Let me also add that I have this thread from Spiceworks and I have tried the disabling of SMM mitigation workaround exactly as it is described over there, to no avail.
I hope that I provided all the details necessary and that someone from Dell can help me. Feel free to PM me for the service tag.
Thank you.

I have it working now by:
In the end, it turned out that it was not directly related to BIOS although I did upgrade to 1.13.0 in the process.
Thank you for your assistance.

Thanks _Diablos_, yes, AHCI is already enabled in F2 -> System Configuration -> SATA Operation.

You should probably change storage mode to AHCI. I'm not familiar with Linux, but the default RAID mode requires intel rapid storage drivers.
