I've just tried to install ubuntu 12.04 dual boot OS with Windows 7 and it finished installing in ubuntu. However, it said that the bootloader "grub.." failed to install. The same exact problem here I receive the error 'grub-install /dev/sda failed' while attempting to install Ubuntu as the computer's only OS. .
