anaconda problem

Bonjour, I try to make a new install of fedora 25. I want to make my own partitionning but it is almost impossible: I create some partitions (/, /boot, /home, etc) but after sometimes anaconda refuses to do anything: it does not add anything and this happens randomly after I created 2 or 3 partitions it stops to add anything. For instance: I create / and swap and /home, after that it stops..... I exit and come back; I create / and /boot and swap and /home and /var, then it stops.... Once I could create all partitions I wanted! Unfortunately anaconda crashed a few minutes after the beginning of the install! Anaconda is really bugged! (For instance: I ask for an install in French langage, when I want to add a mount point, a dialog box opens with a help message in French: "par exemple <<20Gio>> without the quotes" If I type 20 Gio as suggested, anaconda does not know what 20Gio means (Gio=Gib in French), and gives an awfull size, for instance 46Mio or something else...) -- François Patte UFR de mathématiques et informatique Laboratoire CNRS MAP5, UMR 8145 Université Paris Descartes 45, rue des Saints Pères F-75270 Paris Cedex 06 Tél. +33 (0)1 8394 5849 http://www.math-info.univ-paris5.fr/~patte
