[Bug 1668148] Re: Ubuntu live CD installer crashed

[Rocko]

Actually, the disk was completely blank when I started. I wanted to have
a btrfs partition instead of a ext4 partition, so I chose to set it up
manually.

I don't think the bug is invalid, because there are two problems with
the EFI warning message:

1. Go back didn't work when I clicked on it. So I was forced to continue
spending the next ten minutes installing, even though grub-install was
guaranteed to fail, making the exercise completely pointless and
frustrating.

2. The warning message is next to useless, because it doesn't actually
say that you need to set up an EFI partition. It just says there 'could
be a problem', which implies that there might not be a problem, but we
know there is guaranteed to be a problem.

Is it possible to change the warning message so that it tells you that
you also need to create an EFI partition (is 200MB the recommended
size?) for it to work in EFI mode? This would make the installer a lot
more user-friendly (and have saved me a lot of time).
