Grub Customizer does not start

view story

http://askubuntu.com – Installed Ubuntu 12.10 as a second OS. Grub bootloader delivered over Win. Grub smart caught and added Win, only to the end. And by default I need to ship Win. Decided to install Grub Customizer through the terminal: sudo add-apt-repository ppa: danielrichter2007/grub-customizer sudo apt-get update sudo apt-get install grub-customizer But when trying to run Grub Customizer, form appears for a password. After entering the password, nothing happens. What to do? Thank you. P.S. Sorry for my english. I am from Russia and used the Google Translate. :) (HowTos)
