Problem about non booting USB Disk.
The problem can be it not make the usb disk bootable. It same problem if you make the usb disks from Linux that many time they not get bootable.
So we only use Windows for this one thing to make bootable usb disks.
You can also try when boot up press many time F11 to get boot menu and then see if you allowed choose the usb stick.
Example if sandisk usb stick it must come in boot menu.
