I recently bought a Dell Inspiron 15 M3525.
I've been trying to get it to boot from USB to install Linux, but I can't get any USB option to show in the BIOS.
The BIOS it's using is insydeH20 v1.6.0.
In Security, I've disabled Secure Boot, and set Secure Mode to Audit Mode, an option I'd seen as a resolution, but I still couldn't see either a USB or Portable HDD.
I've tried through both USB ports, and even through a Type-C dock, but I'm yet to see a drive show up.
Attached is a screenshot of the Secure Boot section, and a shit of the Advance section. If anyone can provide any next steps, or let me know any further info, that would be amazing.
