If you have the manual for the motherboard, have a look in the section regarding the bios. It should detail where things live within the menus.
Another thing to check is which drive windows decided to put the boot config on. More than once I've seen it put it on a mechanical drive rather than the ssd. Right clicking my computer and going manage gives you access to disk management where it will show you your drives and the partitions that are on them. There should be labels on them under the drive letter/name like boot, system, crash dump etc. The drive with boot on it needs to be the one at the top of the boot order list in the bios. (Even if it isn't the drive windows is installed on)
