I have 14.04 in a test partition, but still using 12.04 as my working install. I do not have UEFI (yet). I had planned a new system a couple of years ago and started following UEFI issues, so I would know what I was doing. But I first bought a small 64GB SSD and old system was so good I put off new system. I still hope to do new system soon.
Boot-Repair does not yet have a trusty version, but I was able to tell it to install saucy version and at least the bootinfo report part worked.
