USB boot doesn't apear in boot sequence

Question

Hi, My dell inspiron 3 s5000 doesn't show the usb boot on the boot menu. Its strange because I use to reinstall my linux always by the same process, but now I can't see it in the f2 or f12 menu... I tried disable secure boot, but did not made appear the USB. I'm sure that the USB was proper prepare, and that the USB connection is working well. I don't know what to do.. I fell that is some problem in the BIOS..
Thanks

You stated that you are trying to use a USB drive that has Linux on it. Just out of curiosity go to the Windows 10 page here and download the media creation tool. That file will create a bootable Windows 10 installation flash drive. Then try to boot from the USB. If it works then you know that there is a problem with the Linux flash drive. Also try various USB ports just to make sure that one of them is not giving you trouble. And if you can boot from the Windows flash drive make sure to exit before you get to the installation screen so you do not install over the top of your files and settings.

What is the correct exact model number of your laptop? Also did you change anything in the BIOS such as Legacy to UEFI or vice versa?
