Windows 10: Install from USB or UEFI? Differences?

I created a bootable Windows 10 installer with the specific Microsoft tool, on an USB pendrive.


Now, when I go in Bios to choose from where to boot to install Win10, I have 2 options about USB port. One is USB and the another one is UEFI....but I just have 1 installer pendrive.
What are differences? Why it find 2 different sources?
Both USB and UEFI options, just shows up when USB pendrive is connected.

Still haven't had a a reply.

W7 is a validated installation on that computer.

This page keeps on getting a pop- up so it is difficult to use.

 

You can use that pen drive to install in MBR or UEFI mode, just pick the one you want.

here is some info from MS on UEFI , if your hardware is compatible id use UEFI to utilise fast boot and faster shutdowns (there are a more reasons than those btw look it up *Smile ) Your hardware has to be UEFI compatible to use the features though as you didnt fill in your specs i cant tell
