I have found the solution after going through a grueling process of unlocking the LVM volume using an Ubuntu Live CD, then formatting the SSD MMC using the same CD, to NTFS.
Afterwards I flashed the BIOS, and then used a Dell OS Recovery Tool to restore it to it's factory settings.
Now its working again. I learned my lesson, and that is to not install Ubuntu on such a newer machine like this that uses UEFI (which is a new technology that is INCREDIBLY annoying).
Thanks anyways for the help, hope this helps someone else in a similar position.
