Comment 5 for bug 1572374

On a related note, if one specifically decides to _not_ create a biosgrub partition and attempts to skip past the message asking you to do so using "partman-partitioning/no_bootable_gpt_biosgrub" it just locks up d-i.

Does anyone know if "partman-partitioning/no_bootable_gpt_biosgrub" actually exists if it does anything? Searching online suggests this as the workaround for preseed but I can't find any evidence of code existing that actually makes this work.
