Comment 106 for bug 1396379

The issue shows up when you have another OS installed on a different drive. Let's say I have Windows installed on /dev/sda, and /dev/sda1 is Windows' EFI partition. I want to install Ubuntu on /dev/sdb, and I want /dev/sdb1 to be Ubuntu's EFI partition. Even after directing the installer to install the EFI on /dev/sdb1, Ubuntu's current installer installs the EFI on /dev/sda1, because it's the first EFI partition it can find.
