I'm trying to dual boot windows 10 and OpenBSD 6.0 on Lenovo Thinkpad L560. I installed Windows 10 first then OpenBSD, copied pbr to windows (C:\openbsd.pbr) using: # dd if=/dev/rsd0a of=/mnt/openbsd.pbr bs=512 count=1 and run bcdedit as mentioned in FAQ. When i try to load OpenBSD it restarts, and black screen with a blinking cursor appears. When that happens I can't even reboot using CTRL+ALT+DEL, I must power down machine by pressing the power button. I can however boot into OpenBSD just fine using installation USB by runing: boot> boot sd1a:/bsd. I even tried using EasyBCD but the problem persists.
