Since you said that this flash drive worked as a bootable device when you had Linux on it, Were you also using the same A to C adapter when you booted Linux from that flash drive? If so, have you considered using the Microsoft Media Creation Tool to create your Windows bootable flash drive instead? Rufus is useful and I use it myself, but it defaults to setting flash drives up a bit differently, so you might find that the Media Creation Tool’s different setup changes things. Basically, Rufus deliberately sets up flash drives to support ONLY Legacy BIOS or UEFI booting. It does this in theory to minimize confusion and accidentally booting in the wrong mode (unless you enable a “cheat mode” to expose additional options). Media Creation Tool creates media in a way that supports booting in either mode.

I realize that you’ve confirmed that this flash drive already works on other systems in its current state, but if you’ve also validated that this flash drive and this adapter both work on this system when the flash drive was set up for Linux, that would suggest that the way Windows was set up on this flash drive is problematic at least for your specific XPS system, even if it works elsewhere.

Thank you for your answer. I created a new Ubuntu live USB Key.

I plugged the adapter and it is not detected by the BIOS (Not listed as an option). Should I proceed with Microsoft Media Creation Tool ? Is there any other settings that can be change ? 
Is there some way to get logs from the BIOS ?

@Jean-R  the adapter itself wouldn't be listed as a boot device.  You'd need a bootable flash drive connected to the adapter from the time the system first started.  Also, where are you looking for this device?  If you're in the BIOS boot order, that's not where you want to look on a UEFI-based system like an XPS 13 9370.  You'd instead want to use the one-time boot menu accessed by pressing F12 during startup.  On UEFI systems, the "permanent" boot options listed in the BIOS have to be registered into the UEFI firmware.  OS installation routines handle that, but temporarily attached boot devices won't show up there.  They WILL however show up in the F12 menu, where the boot option list is populated based on the devices that are actively detected at that time.
