[Bug 1668148] Re: Warning message when installing in EFI mode to a BIOS disk is horribly confusing

[Steve Langasek]

It should be understood that when fixed, this message also needs to
stand alone.  The user has two choices before them, "yes, force" and
"no, don't force".  The system must not assume that the user remembers
anything about what was done before in the installer, or knows what will
come next when picking either of those two options, except what the
message tells them.

It's also possible that the real bug here is in this message ever being
shown to the user at all.  But someone needs to dig into the code and
see it in context of the installer (both ubiquity and d-i) to make that
determination.

Bug description:
  When installing in EFI mode to a disk that is partitioned without an
  EFI system partition, you do get a warning message that this may cause
  a problem and suggests that you go back and do a bios mode install
  instead.  The way that it is worded, and the fact that the button to
  switch to a BIOS mode install is labeled "cancel", is very confusing
  and has lead to hundreds, if not thousands of users clicking the OK
  button instead, and proceeding with an install that is doomed to fail.
  This message really needs to be clarified.
