I got it working!!! It took a while but this is exactly what I did. I will try and shed as much light on the problem I can. Step 1: Download Ubuntu 14.04.2 LTS 64bit from Ubuntu.com I have not tested the newest version so I would suggest using the LTS version because it most definitely has support for UEFI systems. It MUST be 64bit. 32bit does not have support for UEFI systems. Step 2: Download UnetBootin Live Linux USB Creator. This Boot drive creator will make it bootable in UEFI mode which is ABSOLUTELY necessary. Step 3: Use UnetBootin to create the boot drive. Step 4: Press the start menu and restart the PC while holding the [SHIFT] key. This will take you to the advanced boot menu of the windows boot-loader. Step 5: From the advanced boot menu press "Use a Device" and boot from the USB drive. Step 6: Select "Install Ubuntu along side the windows boot loader"(or something smilar) when installing Ubuntu. This will install it correctly. THEN YOU ARE FINISHED!!!! I hope this helps! It finally worked for me! Sources: [URL]
