During installation Grub install fails; Installation Complete?

[Sonic132]

Installer went extremely slowly until the final step. During Grub Install threw a Grub-install failed error. Prompted me to install on another partition. But since I gave Ubuntu the entire drive. There was only sda and sda1. Neither of which worked.
Don't know what else to try.
