Hi,

I CC the list, as we are currently on freeze, but this might require a
fix or at least a big explanation somewhere, my bad for not answering
soon enough. :-(

Testing this I think this warning may be the confusion source.  "All
data will be lost" doesn't include in this case the old ESP partition
(the one in /boot/efi) as that one is not removed when it exists.

To clarify this I propose the attached patch.

Probably it's too late to add new options to that list, or a new
selection step when the partitioning is guided asking if esp should be
kept, as the tests have to be updated too.

I'm throwing a guess here: did you format the root partition but not
/boot/efi the second time?

Happy hacking!
