[05:16] <sourav> Hi, I tried dual boot (Win7 and Kubuntu), the Grub crashed. Now when I switch on my laptop, I don't see any boot option. I tried a few forum/tuturial, but I have one doubt. The commands I tried are at http://paste.kde.org/79477/. I am not able to execute just one command 'sudo grub-install /dev/sda'. It appears, if I can execute this last command, I can fix my boot load.
