[Rolf (thats-unpossible)]

I was able to reproduce this by immediately trying again; and by rebooting and trying again.

I selected manual partitioning, and then I tried to assign a mount point of "/boot" to an existing partition.

[Rolf (thats-unpossible)]

I can reproduce this reliably on my system. But it's blocking me from installing Ubuntu.

I'm sure I can blow away my partitions to avoid this bug, which I will end up doing unless someone wants to gather some debug information about this problem.

Please let me know.
