usb stick acually works and is bootable ? Years ago when I bought w10 with usb stick the stick was broken from the box.. And I wasn't alone with this.
600A->T20->T43->T61->W520 and R61 too.

Also may be that the USB boot disk is made compatible to MBR/Legacy boot process, and the system is set to boot in GPT/UEFI mode only. Or vice-versa (but less likely for a modern PC).
