This will be yet another non-answer to your question, I am fully aware, but maybe it will be applicable to your situation.
I always found dual booting with OpenBSD a little bit cumbersome compared to other OSes. Whenever I want to "dual boot" my OpenBSD client computers I install the second OS to its own usb drive with its own mbr, leaving the internal drive untouched. When I want to boot the secondary OS I just interrupt the normal boot process with whatever F-key and choose to boot from the stick. Has served me well for many years, and makes it very easy to try out different secondary OSes, as long as I consider OpenBSD my main.
