Had the same problem this morning. After problems trying to get the 334.21 NVIDIA driver installed on Mint for a new 750Ti card, I decided to just install the Ubuntu 14.04 and then use a PPA with the driver I'd found. The install went smoothly, I *think*. Part way through, the graphics on the screen were stretched vertically so I could no longer see informational messages or prompts; I just hit ENTER once the installation seemed to be done, and the DVD ejected and the system rebooted after I closed the try and hit ENTER again.
Everything looked normal until the lines
error: symbol `grub_term_highlight_color' not found.
grub rescue>

appeared.
I have NEVER installed grub myself.
