won't let me boot from UEFI USB

Please help! I was so elated when my newly built pc powers on.

I transferred the win10 ISO to an exFAT-4096byte-formatted USB.
The BIOS shows a boot option of "UEFI: (my USB)". That's how I know I have UEFI and not Legacy OPROM (a noob here).

It refused to let me boot from it though.
I tried boot override/ boot option priorities/ CSM- UEFI driver first.
It either shows "exF remove disks or other media" or went straight back to BIOS.
I made changes then "save and exit", but it tells me "you have not made any changes to BIOS".
I tried formatting to NTFS and it shows "no operating system found". Does it not read NTFS!? What is this harassment!?

Side note: My only laptop dvd burner(HL-DT-ST DVDRAM GU71N) is not helping as it doesn't burn DVD-R 16x. I looked it up online and it should burn DVD-RW 4x, but it doesn't!

I hope my thread is in the right place. Thanks heaps in advance!!

I'm using ASUS PRIME Z270-P. Fast boot is disabled but still no luck.
Please see the updated screenshot.

Thank you to all of you who helped! It would appear that mine simply wasn't made bootable.
Calvin7 pointed this out and I can't thank you enough.

P.S. for whatever reason I was able to install win7 several times just by transferring ISO so I never knew.

windows 7 is more frinedly on some situations on some mainboards

win 10 needs a specific type of partition and sometimes must be active, that is why some users need to create the usb via diskpart process, there is a couple of guides on internet explaining how to do it with diskpart
