Default DUAL BOOT OPENBSD WINDOWS 11

Hi,
I'm new of this Forum and I'm a beginner of OpenBSD. I'm trying to install OpenBSD in my new laptop with Windows 11 and GPT partition already present,
I would like to Select between Win 11 Or BSB every times I turn on my laptop.
I red that I is better to install OpenBSD using several different partitions.
I downloded install71 immage and I wrote that on my USB key.
What I have to do to mantein WIN11 and install OpenBSD, I think to create every partitions using GpartedLive, after that I can run install71 YSB key.. Ok and later??? What I ahev to do to finish my procedure.

P.S. If somebody has a better way to realize that procedure, for me I would be great.
"I'm apologize for my eventualy English error."

Windows doesn't normally play nice dual booting these days, I've heard, so maybe try using FuguIta live to see if it (OpenBSD) will work OK on your laptop, first.

The FAQ shows how to use bcdedit in Windows to create a menu entry for OpenBSD:

That's for MBR/PBR. vdavi81 has a GPT configuration. The FAQ states, "rEFInd is reported to usually work. GRUB is reported to usually fail. In either case, you are completely on your own."

I use GPT/EFI and multiboot with Win10, but I simplify -- each OS is booted from its own unique disk drive.

^ Oops. Thanks for the correction.

This should work for a UEFI system as long as OpenBSD & Windows share the same EFI system partition:

First run this command from an Administrator prompt:
Code:
bcdedit /create /d "OpenBSD" {bootmgr}
^ That should return a GUID for the new entry to which will be referred as $guid hereafter.

Now run
Code:
bcdedit /set {$guid} device partition=S:
bcdedit /set {$guid} path \boot\efi\bootx64.efi
bcdedit /displayorder {$guid} /addlast
I can't actually test this though so if somebody could confirm it works I'll see if I can add it to the FAQ.

Ok. I knew, I have to set BCD Windows bootmanager. I have To understant my sdd disk is 512 GB I would like to use more than half, I think to use 280 GB.
With, Gparted is very Easy to create 280 GB non-parted space.
To have, the good OpenBSD installment, How many partition I have to create?
I think, sure:
/ ... root
/boot .. boot
swap .. swap
...
And?
I have 8G of DDR4 ram, I think 4G for swap Is enought?
Then, Wich filesystem type, Do you suggest me?
It's Ok Gparted to create partition? or better use disklabel?

I haven't used the installer for a while but I'm pretty sure it will offer to make use of the largest free space on the disk. Let the installer format the partition, always accept the defaults unless you know better.

I always create a single OpenBSD partition on the disk before running the installer by using GPT fdisk, which is available for Windows or Linux. A single partition of type 'a600' is all that is needed.

OpenBSD will create it's own swap, no need to make one for it.

I created the parttions using installattion tool, It is ok.

The problem is that I didn't copied sets on my usb key.

I need to get a insatallation image, with sets. And I need a tool on Windows 11 to write the image on USB key, to have usb install key.

Somebody can help me. I would downloded the img by OpenBSD official website.

Under Windows you can use Win32 Disk Imager to write an the install image to an USB key.
See https://sourceforge.net/projects/win32diskimager/

Why do you need to download sets?

Sorry,
I red that in install71.img, there is a sets. But when I used dd commando to write USB key, I didn't see a 71 folder.. When I reboot, I select Shell and whit the command ls I can't see 71 folder.

I tried to download install71.iso then I opened it and I saw 71 folder.

I don't remember how to do this on Linux but on OpenBSD:
Code:
adriaan@lenap[~]doas -s
root@lenap[/home/adriaan] vnconfig Downloads/install71.img                                                          
vnd0

root@lenap[/home/adriaan] disklabel vnd0

# /dev/rvnd0c:
type: vnd
disk: vnd device
label: fictitious
duid: 4f2711c05fa49773
flags:
bytes/sector: 512
sectors/track: 100
tracks/cylinder: 1
sectors/cylinder: 100
cylinders: 13608
total sectors: 1360832
boundstart: 1024
boundend: 1359872
drivedata: 0 

16 partitions:
#                size           offset  fstype [fsize bsize   cpg]
  a:          1358848             1024  4.2BSD   2048 16384 16142 
  c:          1360832                0  unused                    
  i:              960               64   MSDOS
Now we mount the filesystem labelled 'a' and do a recursive ls(1):

Code:
root@lenap[/home/adriaan] mount -r /dev/vnd0a /mnt
root@lenap[/home/adriaan] ls -lR /mnt
/mnt:
