Thank,
It works fine. However, grub2-mkconfig tries to detect the installations
available on the computer and get some wrong results that I need to
correct by editing grub.cfg. This is bizarre. How can I get a better
control under grub2-mkconfig?
In fact it just finds installations which do not exist, probably traces of
fedora14 which was installed before fedora 16.
