Update Grub 2 options

As a follow up to my previous post Ubuntu Server 14.04 fun I was asked how to update the Grub2 file. It's really very easy. Use a text editor to open /etc/default/grub like so:
sudo nano /etc/default/grub
Then find the line that says GRUB_CMDLINE_LINUX_DEFAULT="" and add nomodeset inside the quotation marks.
If you do use nano then you can press Ctrl-o and Ctrl-x at this point to write and exit.
Then run this command:
sudo update-grub
and that should do it.
