Comment 42 for bug 484252

Dmitrijs, I believe you have some expertise here; can you have a look at fixing this?

We don't necessarily need to support installing to a single partition on the disk if that's error-prone in other ways, but we should definitely make it clear that the entire disk will be formatted. I've experienced (non-data-loss) problems myself before where selecting a partition on the target USB device didn't do what I expected, so I think the selection screen needs clarifying.
