Mint 17.1 - installation reverts to Grub - UUI

I'm attempting to install Mint 17.1 and have succesfully used Universal USB Installer to create a bootable USB stick. When booting up Mint the pleasing loading screen fails to make an appearance and instead the Grub menu is shown. How should I proceed to install Linux Mint on this machine? I have attempted the same proces using YUMI but in this case the machine reverts to the BIOS settings instead of loading Mint / Grub from the USB stick. To clarify, I'm not intent on dual booting with Windows 8 but replacing the Windows installation with Mint.
