Public bug reported: During installation, users are asked to specify what harddrive they would like to install on, or in the advanced mode, what harddrive that would like to install the bootloader on. At least with EFI, this selection seems to be disregarded.
This has happened to me three different times. The first two times, I was installing Ubuntu onto an external harddrive, and after very carefully instructing it to install the bootloader onto the external harddrive, it mangled EFI setup of the internal harddrive both times (once each on machines with Mac and Ubuntu installed internally). The third time was today, where Windows was on one harddrive and I was installing Kubuntu on a blank harddrive that I had just added. I intended to use the new, Linux harddrive primarily, and I set my BIOS to boot from it, but I didn't see any reason to take the old one out of the computer. After installing, the system would not boot, and it was only when I tried to boot into Windows that I found that grub had been installed on the wrong harddrive. I don't have an exact version of Ubiquity, but the Kubuntu 15.04 image that I downloaded today did this. To be clear, the first two times I was using Ubuntu (not Kubuntu) 15.05.
