Re: Dual booting - can't boot OpenBSD from Windows 10 bootloader
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.

Neither do I, but I have Grub2 (from Debian amd64) and OpenBSD amd64 ;) You don't need to install any Gnu/Linux system to have bootloader from Gnu/Linux. You just need to prepare pendrive to boot liveCD *once* and install lilo or Grub2 bootloader, but not need to install the whole system. I must admit that I have additional 50MB partition with ext2 filesystem for bootloader.

Thank you all for your asnwers. I cannot use grub or lilo as some of you pointed out beaceuse grub is i386 only and lilo isn't even in ports, and I don't have linux installed. I don't want to use quemu, vmm/vmd or any virtualization if at all possible as that would degrade performance, that isn't that great to begin with on lowe power i5(U) especially using Windows and Xilinx. Unfortunately I think my model of Thinkpad doesn't have space for another drive as it's middle range L series not higher end T seris.

Do you have a way to use two drives? e.g. a minipcie/similar SSD and a 2.5" hard drive? I'm doing this on my thinkpad, it gives a convenient way to dual- boot using the BIOS boot selector, and is a lot easier (especially when you need to update the OS) than single-disk dual boot. > 2016-09-23 14:04 GMT+02:00 Eric Furman : >> NO professional dual boots OS's >> There is NO REAL reason to dual boot ANY OS's What nonsense.

You'd want a Windows or Linux host with the other two in VMs. Personally I just triple boot using LILO for chainloading and it works fine, even with the OpenBSD partition past 128GB. (Sorry about the direct reply Karel, didn't pay attention to the To field.)

Apart from those who are sick and tired of Windows, and sick and tired
of Microsoft controlling their PCs. Many a professional will use
Windows to do their work-related work, and the Linux distro to do the
rest of their stuff.
> There is NO REAL reason to dual boot ANY OS's
See above, although with the event of vmm(4) and vmd(8) and other
virtualisation, I predict that eventually your point will be valid, as
people can simply run the secondary OS in a virtual environment.
> This is why OpenBSD has stopped supporting such nonsense.
Just because OpenBSD doesn't support it doesn't mean that it is "such
nonsense." However since there are plenty of other boot managers
out there, many of which support this configuration, there is no need
for OpenBSD's boot loader to support it, as this just duplicates work.

Then there is no need to shout at everyone.

Re: Dual booting - can't boot OpenBSD from Windows 10 bootloader
I've been looking for a solution, and then stumbled on this:
https://marc.info/?l=openbsd-misc&m=138477729520448&w=2
So it looks like OpenBSD's bootloader needs too be in first 128 GB of
the disk. As for dualbooting I want to use OpenBSD
but I'll sonn start college, and we have digital logic class in firs
semester, and I will be required to use Xilinx ISE on their
machines so I want to have it on my PC too. As far as I know Xilinx
ISE supports only Windows and Linux, and OpenBSD
6.0 no longer supports linux_compat, so that's why I went with dual booting.

This config is questionable as there is no 'lsb_release' command
either on Windows (huh) or OpenBSD. I have no idea why you share
a config from Debian here, ie. you have tripple-boot?

Re: Dual booting - can't boot OpenBSD from Windows 10 bootloader
NO professional dual boots OS's
There is NO REAL reason to dual boot ANY OS's
This is why OpenBSD has stopped supporting such nonsense.
