Can't boot from USB

Hello everyone

I'm actually running Ubuntu on an Asus X501A w8 native, I'd like to install another os from USB drive (since it has no internal cd reader) but I cannot find the USB option in boot (bios version: 2.15.1226) but I did it in the past and it did work well.. USB were detected and so the external DVD reader... What happened? :( now the only options available are the internal hard drive and the network device no other options...

    Does your BIOS have a "add to boot list" option? On my last build i had to go in and select different items to add to the boot list before i could select them. Also, what format is your USB drive, and is the OS file in .iso format?

    I formatted the usb in fat32, yes it is a iso image downloaded from the ubuntu official site with unetbootin, I did utilize the same usb in the past and it did work well... are you in knowing of a method to fix the eventual bios errors/ to fix the fact of not detecting the usb?

    Thank you for your answers!
