I recently purchased a Dell Inspiron 15 M3525. I'm attempting to boot from USB to install Linux, but the BIOS doesn't display any USB options. The system is running insydeH20 v1.6.0, and I've disabled Secure Boot while setting it to Audit Mode—a setting I thought would help. However, neither a USB drive nor a portable HDD appears in the BIOS. I've tested both USB ports and even a Type-C dock, but nothing shows up. I've attached screenshots of the Secure Boot and Advanced sections for reference. Any advice or additional details would be greatly appreciated.
