Hello astheroth. Check this nice tutorial: Dual booting Linux and FreeBSD. Good luck!

I dual-boot Devuan and FreeBSD...well, actually I multi-boot several Devuan-based distros and FreeBSD. The way that I did it may be unconventional though...

I reformatted my hardrive with all of the partitions that I knew I wanted. I formatted the partition that I wanted to use for FreeBSD as fat32 (which was /dev/sda3). I then installed my main OS on /dev/sda2 (/dev/sda1 is swap). I also used Grub.

Installed FreeBSD on the fat32 partition, and rebooted to my main OS. Added the following to the file /etc/grub.d/40_custom

menuentry "FreeBSD" {
set root='(hd0,3)'
chainloader +1
}

Notice the (hd0,3) above...the 3 is the number of the partition that I installed FreeBSD on...your partition number may vary.

After adding that to the file, I saved and closed it. Then I ran...

update-grub

Rebooted, and FreeBSD was listed in the Grub.

This worked well for me, but I don't know if it's the best method.

Edited to add: I also chose UFS for my FreeBSD install rather than ZFS.

Hello

Read 12.2.1. The Boot Manager: https://www.freebsd.org/doc/handbook/bo … ction.html
I have done this but it was a while ago and it is all blurry now. I can tell you this:
1. Install Devuan first without GRUB
2. Then, install FreeBSD with boot0
This ought to do it. It is fairly easy as long as you don't install GRUB.

Dualboot Devuan with FreeBSD

Well, Days ago I decided to give the Jump from Linux Mint 17.03, my main distro since 2015 to Devuan ASCII. In my last configuration I had installed FreeBSD, Windows7, and Haiku alongside Mint. To Install Devuan I decided to format all the HD and then adding the other OS. My first one was FreeBSD, but Devuan grub says it doesn't recognize the filesystem.

At the moment my /etc/grub.d/custom_40

menuentry 'FreeBSD' --class freebsd --class bsd --class os {
insmod part_msdos
insmod ufs2
set root="(hd0,msdos1,bsd1 >)"
kfreebsd /boot/loader
}

Perhaps the fourth or fifth combination I tried

Another important data.

Making

fdisk -l

gives:

#  fdisk -l

Any idea? I think that devuan's grub doesn't support UFS but, I am not sure
