Okay, thanks for the information.

What I had was MSW8 set up on a straight GPT formatted, UEFI BIOS, DRM
enabled netbook (HP Pavilion-something). Took a restore DVD set and
confirmed that I can re-install MSW8 by just walking on top of
whatever is on the disk. Couldn't find options to set up MBR or to
install to a pre-partitioned disk.

So I'm doing entirely without MSWindows right now. (No feelings hurt,
I prefer it that way, really, except there's a project I eventually
want to pick back up involving the SH3 processor, and Renesas seems to
only support tools that run on MSWindows. And that kind of stuff. If I
need it bad enough I suppose I can buy a boxed MSWOS, but I'd rather
not pay MS any more money than I have to.)

I've got openbsd running in the inboard drive, MBR/DOS partitioned.
Also got it running outboard (USB3, ugh). That is another possible
option, really, when I need MSWindows, run openbsd from outboard (and
be careful not to pull too hard on the cable ;-).

I've enabled the current kernel GPT support (re-compiled, etc.), but I
haven't been able to tell whether that actually buys me anything
without GPT utilities. (My son has a similar, newer HP Pavilion
netbook with Ubuntu installed in a GPT partition, but he won't let me
boot openbsd outboard to try to see what GPT support in the kernel
enables. No time to let me play on it, he says.) So, I'm planning to
temporarily move things to the outboard drive and re-install MSW8 this
week to see what happens.

I don't think I'm going to go so far as to spoof the MBR, however.

I'm thinking, just
(1) shrink the MSWindows partition,
(2) make a partition in the empty space,
(3) and see if I can get disklabel in a bsd.rd image built with GPT
enabled in the RAMDISK confiiguration to find that partition and let
me install there and boot from it.

If that fails, my tests so far indicate that the outboard openbsd
running the GPT enabled kernel is still not going to let me see the
GPT partitions in the inboard drive, but I'll check that, of course.
If it does, I'll try something like unpacking it by hand. (Even more
opportunities to learn from failures, of course. :)

If I get stuck, I'll probably set GPT aside for several months and
focus on getting the WIFI on this thing running. In fact, if someone
would tell me that what I'm trying to do isn't supported yet, I'd be
happy to work on the WIFI first. I'd like to be able to access the net
from this box at work, and they don't want me plugging into the wired
LAN, but have no problem with logging into the wifi network.

Re: GPT should work? (was Re: Dual Booting OpenBSD vs Windows7)

[Peter Kay]

 OK, I should be more specific - what I got working was an OpenBSD install on a 
GPT disk which included Windows 7 installed in MBR mode. This involves some 
nasty hackery with OpenBSD fdisk, and was done at the time because I thought 
I'd be installing OS X on the same disk.

What I haven't explicitly got working is Windows 7 in GPT mode on a GPT disk, 
alongside OpenBSD, because my BIOS only supports the ancient 32 bit EFI 1.1 
(Intel server motherboard)

To recap :

Vista SP2 x64 supports GPT installs, as does Windows 7 x64 or better.
OpenBSD does not understand GPT at all
FreeBSD does
NetBSD did/does(?) But only to the point of recognising, not installing on the 
disk. The worst of all worlds.

When a GPT disk is created, in addition to the GPT format, it creates a 
'protective MBR' where up to the first 2TB (limit of MBR) is covered by a 
partition of type 0xEE. This is to stop older programs overwriting bits of the 
GPT disk.

It is possible to manipulate this protective MBR, and therefore install 
OpenBSD. Windows is remarkably tolerant of weird hard disk partitioning 
formats. OpenBSD doesn't know, or care. Linux does, however - it will see and 
use GPT.

I run everything off Xen at the moment, which does now have an EFI BIOS 
supporting GPT I believe. It will take me a little time to allocate a disk 
image to install both 7 and OpenBSD on and test if it can be done. I'm fairly 
certain it can be done, but off the top of my head I can't remember if a GPT 
install of 7 has the same boot capabilities as MBR.

In any case, there you go. A GPT disk can definitely support a hacked on MBR 
install of 7 and OpenBSD. GPT with GPT Windows and MBR OpenBSD I'd have to 
double check

even left 1st ans 2nd partition for dummy m$ windoz but it failed...
windows 8 said the same for me... m$ likes only m$dos partition table...

Also have found on M$ technet that during boot need to do some magic stuff
and get cmd. Call out part tool and create M$ windoz gpt... but for that i
had to remove Debian. so i said sorry bill but Ian Murdok i respect more...

If some one knows for 100% sure and can film windoz installer installs to

Peter, if you have done this on a GPT formatted disk, I would like some clues.

My first fumbling about a month ago couldn't find a way to get the
installer to recognize the GPT partition scheme on the drive, so I
copied out the restore DVDs and wiped the GPT and used the legacy 4

Re: Dual Booting OpenBSD vs Windows7

The method in the OpenBSD docs is a no extra tools required method. BCDedit
makes it even easier.

1) Install Windows 7/8 on an MBR disk. GPT should work but requires more
effort.
2) As part of 1) create a partition for OpenBSD
3) Use OpenBSD fdisk to change partition type to A6, install on that
4) Do not install boot menu to MBR
5) Use BCDedit on Windows, add the OpenBSD partition
6) (optional, Windows 8) set boot menu to classic mode

Please do.
you are not correct.
You created a boot.ini file.  Nowhere under "Windows 7" is boot.ini

The documentation is correct, and the first paragraph of this section is

"ERR M" means that the pbr successfully loaded a file into memory, but
it wasn't a valid ELF executable. Most probably, this means that the
pbr you're using refers to the wrong inode.

You said something about a "second system"; did you copy openbsd.pbr
from one system to another? installboot patches the pbr with the
location of /boot, so you need to create openbsd.pbr on the same system
you're using it on.

could you state a bit better what your problem is? I have dual-booting

Are you getting the initial windows boot loader with the choice of your 
OS or not? Check 2) below (bcdedit.exe)

If you do, do you get a failure then? check 3), copy openbsd.pbr into c:

In short:

1) shrink: worked for me even with windows tools
2) set up BCD: worked for me as in FAQ, except that I missed another 
command to actually add the new entry

3) remember to generate and copy openbsd.pbr !

Dear OpenBSD users,
As I reported my issue was resolved by bootice and grub4dos.
But on the second systems this procedure can not resolve dual booting.
At the section of 4.9 of FAQ#4 told that creating openbsd.pbr file by *dd
if=/dev/rsd0a of=openbsd.pbr bs=512 count=1.*
Is that command was 100% true?
I recreated *openbsd.pbr* again but this issue was repeated and I think
that command must be change!

This needs interpolation for gpt/guid partitioned disks, and requires, as I
understand things, a custom option in the kernel, among other things. I'm
trying to learn how to do this with MSWindows8 right now, and I'm learning
a lot of useful stuff.

Boot floppy is for really old hardware. Re-interpret that as using an
entirely external drive.

And a second hard disk is not necessarily a bad idea. In fact, I'm using a
USB3 external rotating drive for some of the playing/research I mentioned
above. Built the kernel and userland from source entirely on the external
drive. Mis-calculated about /usr/xenocara, so I made /usr/xobj my last
partition (on /dev/sd1p). Now I'm starting over and should have xenocara
built from source in about three to six hours.

Yes, it builds faster on the internal drive. But that doesn't seem to be an
option for you right now.

But, as a thought, have you made an MSWindows full system restore DVD along
with backing up your data?

NTLDR was dropped by Microsoft before MSWindows7, so, if that's what you
mean, yeah, don't bother with NTLDR.

If you are trying bcdedit for MSWindows7, are you sure you got the disk's
GUID copied correctly from the results of the bcdedit /create step?

If you are talking about the other boot loaders, they are independent of
the 32bit/64bit issues.

If your MSWindows7 is on a GPT partition, things are not going to be easy.
You'll really want to consider using an external drive for the time being.

Anyway, anyone here with time to help you needs more information about how
and where things are not working for you -- error messages that you may
have to copy into your mail by hand, etc.

I had read this FAQ page more than 10 times.
It have wrongs hints:
suggestion 1 about active partition did not work for me
suggestion 2 worked correctly but need a second media.
suggestion 3 is completely wrong!
I have tested more than 3 times.
maybe it wrote for specialy windows 7
suggestion 4 identify some tools that run on 32 bit windows and now Only Grub
maybe can resolve my problem.
At now I work on GRUB and wish to resolve the dual booting.
