Comment 1 Yves L'ECUYER 2016-12-11 20:27:10 UTC 
So the bug turnaround was:
To start the system in single user mode, by adding the word single at the end of the line: linux  /boot/vmlinuz..., for the choosen entry of boot grub, when you go in edit mode, at first grub step

Once logged in in single usermode, the system propose to look at 
journalct -vx.

I just do that piped in less
# jpournalctl -xv | less

and then searched carefully the last error message.

I just see in particular some thing like:
systemd-update-done.service has begun starting
< date/hour> <myhostname> systemd-update-done[775]:
Failed to update timestamp on
/etc/.updated: Permission  Denied
..... : Main Process exited
...
Unit systemd-update-done.service has failed
====
So I edited /etc/sysconfig/selinux
and set:
SELINUX=permissive

I also read, before rebooting, but after the SELINUX policy modification, the content of:/etc/.updated
There is only comment"This file was created by systemd-update-done...." !!!!

Then I rebooted the system in permissive mode, and then the system-upgrade installation of the downloaded Fedora 25 has started without any more problem.
Of Course at the end of installation I set SELINUX in Enforcing mode Again !
And now my Fedora 25 is working  !
Comment 2 Yves L'ECUYER 2016-12-11 20:34:27 UTC 
Well in the description above, when I say " reboot continuously" means
After the initial reboot processed by :
# dnf system-upgrade reboot

I just do nothing, grub choose the default kernel entry of Fedora 24,
and when the dnf system-upgrade tried to continue his job, the system make a shutdown because of this fatal error described above !

So while first I was  looking  my PC during 10 mn, without doing nothing, I just see it rebooting ten times! Before I decides to try to find an issue !
