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: # /dev/rsd0c: type: SCSI disk: SCSI disk label: WDC WDS500G2B0B- duid: f2adf57b4715cd30 flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 255 sectors/cylinder: 16065 cylinders: 60801 total sectors: 976773168 # total bytes: 476940.0M boundstart: 455473152 boundend: 976769024 drivedata: 0 16 partitions: # size offset fstype [fsize bsize cpg] a: 254539.0M 455473152 RAID c: 476940.0M 0 unused i: 500.0M 2048 NTFS j: 221898.0M 1026048 NTFS Disk: sd0 geometry: 60801/255/63 [976773168 Sectors] Offset: 0 Signature: 0xAA55 Starting Ending LBA Info: #: id C H S - C H S [ start: size ] ------------------------------------------------------------------------------- *0: 07 0 32 33 - 63 221 30 [ 2048: 1024000 ] NTFS 1: 07 63 221 31 - 28247 27 2 [ 1026048: 452763710 ] NTFS 2: 27 28247 58 36 - 28351 195 4 [ 453791744: 1679360 ] Win Recovery 3: A6 28351 227 37 - 60801 15 14 [ 455473152: 521295872 ] OpenBSD
