Hello ! This post worked perfect for me (Shuttle UEFI only machine with a 64 GB SanDisk Extreme USB 3 stick). BUT as written there, use [OpenBSD] in disklabel instead whole disc.
I had the problem, that fdisk reports, that the used device was not there even console log shows, that it was there. Solution : run fdisk -i -b 960 sdX on a working -current machine and, reboot - select install ... and again at disklabel use [OpenBSD]. Continue as described in the blog post. Am 13.
