+1. I've seen a LOT of online problems reported because Ubuntu installs
in one mode on a computer with another OS installed in another mode.
Usually the existing install in EFI mode and Ubuntu installs in BIOS
mode, although sometimes it's the other way around. My own suggestion
is:

1. Ubiquity should look for an existing OS installation and try to infer its 
boot mode. This is easy with both Windows and OS X (except for naughty 
Hackintosh setups). It's harder for other Linuxes and BSDs.
2. If Ubiquity is booted in a mode that doesn't match inferred boot mode for 
the existing OS(es), put up a warning that briefly explains the issue and 
provide a URL to a document with more details. There can then be options 
depending on the boot mode:
  * If in BIOS mode, the options should be to abort or proceed with a BIOS-mode 
install.
  * If in EFI mode, the options should be to abort, to proceed with an EFI-mode 
install, or to switch to a BIOS-mode install.

All this said, I don't know how difficult it would be to modify Ubiquity
to provide these options. I just know that the lack of such options is
continuing to cause problems, even with 14.04. There's a whole cottage
industry of tools to fix the problems, like Boot-Repair.
