@sep33
Linux is not supported on ANY Dell model unless your model shipped with Linux from dell.
"KDE Neon Linux" is not one of the many supported versions.
There is linux support from Dell, Suse, Canonical, Redhat, etc but its not free.
dell support kbdoc 000138246
Dell has support for Linux Support Site
Dell has included Linux self-help pages on its Support Site:

Hello @sep33 , were you install from a usb device? This simple method works for me.
Download and Installation:
1. Copy the downloaded file to a USB drive. The USB drive does not need to be bootable device.
2. Insert the USB drive into any USB port.
3. Power on the system.
4. At the DELL logo screen, press F12 to access the one-time boot menu.
5. Select BIOS Flash Update in the Other Options section.
6. Click the ... button to browse the USB drive to locate the downloaded file.
7. Select the file and click Ok.
8. Verify the existing system BIOS information and the BIOS update information.
9. Click Begin Flash Update.
10. Review the Warning message and click Yes to proceed with the update.
The system restarts and displays a progress bar at the Dell logo screen. The system restarts again when the update is complete.
