Thank you again for all your suggestions and answers. I finally made
it to work. I first shrunk windows partition to be below 256 GB. Then
as it says in this thread:
https://marc.info/?l=openbsd-misc&m=138477729520448&w=2
I changed BOOTBIOS_MAXSEC in sys/arch/amd64/include/biosvar.h from ((1
<< 28) - 1) to ((1 << 29) - 1), and rebuilt the system follwoing
release(8), copied installboot binary to /usr/sbin overwriting the old
one and successfully installed biosboot. I can finally boot OpenBSD
directly from windows bootloader without using grub.
