Ubuntu install fails on grub install

[Matthew Gardiner]

Installing Ubuntu 12.10, USB image created with Unetbootin. Booted first to desktop, then installed from installer link. Grub fails to install on /dev/sda1 (SSD), given opportunity to install to another partition, selected Ubunut root partition (/dev/sdb2) - same error.
