My laptop wont boot from USB in legacy mode. I disabled fast & secure boot. How do I boot Ubuntu from Flash?

I entered BIOS and turned off secure boot and enabled legacy mode. I changed the boot order to check for a USB to boot from first. I unchecked fast startup option in the power settings in Windows 10.

I have tried to boot from USB using bot 32 and 64bit versions of Ubuntu that I burned onto a 32g ONN thumb drive using the Rufus program.
