Thank you for giving me a direction. I have added missing ending double qoute and restarted computer and it worked. Then I run command "sudo update-grub" which was written at the begining of the file:
# If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. Then I restarted computer for the second time, but now it is frozen. On my screen there is a warning issued by monitor that video mode is not recomended, because it is not 1680x1050 (native mode of my lcd monitor). I am now trying to boot live from cd... I was following steps from the address https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows and now everything seems to work. Grub menu looks a bit different than earlier. Thanks again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/815240 Title: package grub-pc 1.99~rc1-13ubuntu3 failed to install/upgrade: ErrorMessage: podproces installirana post-installation skripta je prijavio grešku sa statusom 2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/815240/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
