I'm using a Dell Inspiron 5590, it came with Windows, I want to install Ubuntu instead. I downloaded the 18.04.5 image file and made a bootable USB device with Rufus following the ubuntu tutorial. The problem is, when booting, the USB device doesn't show in the Boot Options.

What I've tried:

  • Tested in USB ports 3.0 and 2.0
  • Tested flash drive in another notebook (It works)
  • Tested with and without Secure Boot.
  • Tried two "builds" of the bootable USB: Partition scheme: MBR + Target system: BIOS or UEFI AND with Partition scheme: GPT + Target system: UEFI (non CSM).

Also:

  • I'm not looking to dual boot this, just linux is fine.
  • USB Boot Support is enabled
  • I didn't tried with Legacy Boot, because the BIOS says that this mode is not supported in the platform.
  • Contacted Dell before purchase to be sure the hardware was compatible with Linux. (Also contacted the Dell support for help, useless in this case)
  • BIOS is up to date.

What else can I try in order to have my bootable USB to be recognized by the Boot Manager?

Well, if anyone is facing similar issues, I solved mine by replacing the USB flash drive.

It was a Sony 16gb, it works fine both within the OS and as a bootable device in other notebook, but for some reasons in this notebook it didn't. Replaced with a SanDisk 16gb and it worked.

Some BIOSes have difficulty with USB sticks over 4 GB. If the USB stick that you have tried previously is larger than that size, try one that is less than 4GB.
