[Solved] Keyboard language problem when insert password

[SevenTai7]

Hi guys, I have a strange but huge problem:
I've set my password as "ù" to make everything quicker because i had to install a lot of stuff.
The problem is: when I have to insert my password, the keyboard is set in U.S. language, so when I press "ù" I'm actually pressing "/". I've discovered this in the Clover main menu, while i was trying to write.

This happened me on El Capitan boot, for luck I have another boot with Mountain Lion. I've tried to change the file "com.apple.HIToolbox" with the ones in preference under the folder "user" but the problem still.

The question is:
There's any way to change the password or the keyboard language, with the other boot maybe?

Thanks to everyone and sorry for my english

Try to rerun Setup Assistant maybe (search google).
