I can confirm that the workaround by Florian Albertz is working just fine. Moving Elementary files into the Ubuntu folder worked just fine. For those who don't know how to do this, I just installed the Disks tool via Software Center in the live OS, mounted the FAT partition in my disk and then just moved the files using FIles. Remember you need to have secure boot disabled to access this partition. Thank you a lot for the tip :)
