Actually i did a full install of win 10 64 familly.
I let win 10 install and create partition by itself.

Anyway, in a previous post i sayd the :

Windows 10 can't repair your pc, see srttrail for detail was fixed, but it's not.

I still have this problem even if it's a fresh complete install.

I used shift then restart to try the repair environment.

I dunno what the problem is with win re. i will try to post the result from srttrail log.

cause initial trouvée:

"la version de windows est incompatible avec l'outil de redémarrage système"
In english it's: "The operating system version is incompatible with Startup Repair"
