Ubiquity invokes the grub-installer bash script to perform the actual boot loader install stuff - it reads the the grub-installer/bootdev debconf value to know where to install the bootloader.
There is some logic in there to find a default boot device which I suspect is how it's picking the first partition of the first drive in the machine, but I'm not very good at debugging shell scripts so I couldn't find a reason as to why it would be using that logic in the first place since grub-installer/bootdev is already set correctly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1396379 Title: installer uses first EFI system partition found even when directed otherwise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1396379/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
