I remember the following as the steps not mentioned in the FAQ that helped me
get it to work. All with MBR and Windows 10.

1. Shrink the main partition in Windows disk manager and create a second
   partition.
2. In the OpenBSD installer, run fdisk and change the type of the second
   partition to OpenBSD (A6), otherwise keeping same size/offset.
3. For softraid crypto, follow the FAQ for installation. You should create the
   RAID partition as 'a' on the OpenBSD part of the disk, leaving (in my case
   'i' and 'j' intact.

If the above steps help you or your friend to set it up, we can see if an
addition to the FAQ may be worth considering.

Here my disklabel and fdisk from that setup:
