In doing more research, I am finding an error that might be cuasing

Manually putting the lines in the grub.cfg file, I can boot to the windows 10
with no problem.
Just tried to mount the windows partition from the fedora 25, and get the
following error??
/sbin/mount.ntfs: symbol lookup error: /sbin/mount.ntfs: undefined symbol:
ntfs_xattr_build_mapping
Did a dnf reinstall of ntfs-3g, and got the same error.
Just downloaded the ntfs-3g_ntfsprogs-2016.2.22.tgz which seems to be the
same version, did a configure, make and then make install. Was then able to
mount the partitions, and just now ran the grub2-mkconfig and it worked.
So, not sure what was causign the symbol lookup error??

Then you really
should report the error to bugzilla.redhat.com (assuming
you have a free account there).
