So i'm not good with Linux at all but two things popped into my head when reading your post. First off when you boot does it get anywhere or is it immediately stating that the boot device failed? If so, does the E7450 have secure boot enabled in the bios/uefi? I have heard a ton of people state that if secure boot is enabled, nothing but windows will work. Second if it does start to boot but then fails, maybe its a configuration problem with the linux distro, sort of like how you can't transfer an installed copy of windows from one computer to another because the drivers don't match. If that is the case you may have to install linux fresh on this new machine.
As beamermt79 stated, UEFI could be the problem. If you can't turn if off, try searching for ubuntu UEFI install; many, many pages talking about this, and how to install.
Another issue is trying to install 12.04 on a newer system. You might try using 14.04, as it has updated drivers for newer hardware, that 12.04 lacks.
