crash

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. . When I tried to restart my computer, it went to the hp screen since my computer is a dv6 hp laptop and then it goes into this black screen with no words or any buttons will work. There is just a blinking underscore that seems like it'll allow me to type but makes error sounds when I type. Is this because I possibly partitioned my memory incorrectly? Any help would be greatly appreciated. I'm very desperate. ANY HELP would be great. Thanks.
