If you don't need to or don't intend to share the disk with other operating systems, answer "w" here to use "MBR" partitioning or "g" to use "GPT" partitioning. The installation program will then create a single partition spanning the whole disk, dedicated to OpenBSD. > Additionally, I have noticed that (per warnings in the installation > program) GPT partitioning does not work on my system.

I never had issue with GPT.
