No usb boot option on boot menu

Hi guys, I'm new and I think you may help me with this trouble.

I have to install Linux MX on a LATITUDE E5410 and the only way I can is via USB but when the boot menu is displayed there is no option for usb boot althought boot sequence (in the BIOS information) shows that I can boot from USB.

I have upgraded the BIOS from A10 to A16 but anything seems to change and only allows me to boot from HDD, CD or NIC.
