The question allowed a user who is also a mind reader and knew what the options meant (since the actual text of the message was useless for understanding this) to switch to a bios mode install.
The fact that this message was shown at all, ever, was a bug elsewhere in the installer. This will be fixed so that we never again hit the path where this message was previously shown. Therefore there is no value in reintroducing this opaque message. ** Changed in: partman-efi (Ubuntu) Status: Triaged => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1668148 Title: Warning message when installing in EFI mode to a BIOS disk is horribly confusing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/partman-efi/+bug/1668148/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
