Can you be more specific on what you mean by "downloaded the windows 10 tool?" You should follow the link provided, where an official Microsoft software will download the windows 10 image and has an option to create a USB stick.
If this is correct,then make sure you're doing the right thing to boot into the stick. Do you see the stick as an option in a boot menu? If this is a newer (UEFI) board you may see two entries, like "USB drive" and "UEFI USB drive" or something of the sort, in which case make sure to select the UEFI option.
