Sorry for the very late followup, but after clean installing F12, I see
that the F12 installer has again switched the active partition from the
Windows partition (/dev/sda1) back to the Linux /boot partition
(/dev/sda2).  I'll have to switch it back again to avoid future problems
with Windows updates.
