Have you tried to edit the windows boot loader and somehow boot the openBSD? I have done that approach ages ago where grub was on second disk and I made windows boot loader (legacy mode) to boot from the next disk and then grub kicked in. Of course , you can try the opposite - somehow openBSD to boot the windows :) Best Regards, Strahil Nikolov
