USB boot Lenovo Ideapad S340

Question

I have spent days trying to get an Lenovo ideapad S340 boot from a USB.

Would someone care to walk me through step by step?

I have searched on the internet, changed BIOS settings, created USBs (universal usb installer, unetbootin ) and am going round in circles.

I do have technical background and can follow instructions, but need some guidance to avoid the pitfalls.

I am stuck with getting this USB to work.

Thanks user535733 and karel. It worked eventually :) by using Rufus to build the USB. The steps were picked up from the tutorial: https://ubuntu.com/tutorials/tutorial-create-a-usb-stick-on-windows#1-overview

another page that really helped is here: https://forums.lenovo.com/t5/Lenovo-U-and-S-Series-Notebooks/S340-15IWL-Can-t-Legacy-Boot-from-USB/m-p/4477110 its about changing settings in the ROM during startup.
