@guiverc That's pretty cool, didn't know about that but followed instructions and the options have been loaded in. Is the correct way to set the options permanently to edit them in /etc/default/grub?

Yep - here is a reference link if you'd like more info (wiki.ubuntu.com/Kernel/KernelBootParameters); which includes the useful hint tosudo update-grubto cause re-build your grub file after you've edited.
