I am trying to install Rocky 9 using bootable USB on DELL Inspiron 14 3420 laptop but the laptop boot sequence does not detect any USB device, even I tried USB DVD ROM which also does not detect in the boot sequence. I tried multiple USB storages. I tried the blank USB (formatting in the Windows OS) just to verify whether boot menu detect the USB storage. Nothing worked.

I created the bootable USB using Rufus and tried different options MBR/GPT with FAT32/NTFS but no luck.

The BIOS on this laptop is very basic in 4 tabs and only option in the BIOS allow to modify the secure boot disable/enable. There are no other boot options available in the BIOS.

Any help would be appreciated.

Thanks
