Choose "Something else" at install options, select a partition change the FS to ext4, select format, set partition to be /. Do not change the size.... size gets changed anyway, ( I lost 8M)

I think what is happening is that ubuiquity reads the partition size and displays it in Mb. It is rounded or truncated to make it fit the display. the user doesn't change it, but the size never was the same as the original partition and so the partition gets resized.

What should happen is that if the given size is the same as before and after no resize should happen. That is ubiquity should compare what the user enters with a recalc for display rather than comparing with the actual size to determine if the size is actually changed.
