Unable to dual- or multi-boot GhostBSD

Post by londoner » Mon Jul 15, 2019 5:15 pm

Hi everyone. I am completely new to the world of BSD, but consider myself to be a fairly well-experienced user of Linux. Wanting to expand my knowledge, I recently decided to have a closer look at BSD.

I downloaded the 64-bit .iso file of GhostBSD 19.04 MATE and verified it was OK with the sha256 sum. After trying it in a VM on a laptop, I decided this was the BSD variant I wanted to use for my project.

From herein afterwards, everything was done on a desktop system with a 500 GB HDD using a GPT partition scheme. All booting and installation was done in 64-bit UEFI mode. Both Secure Boot and Fast Boot were disabled in the UEFI.

I have setup many multi-boot systems before, both with and without MS Windows. In particular, about 18 months ago I created a multi-boot system with 10 Linux distros on the same HDD. This time I decided to update that setup and add Windows and GhostBSD to the mix.

I started by installing GhostBSD on its own, first in ZFS, and then in UFS Full Disk configurations. Both times the install and booting were successful. That would seem to rule out any hardware related problems. Then, just to see what would happen, I installed Windows 10. As expected it wiped out the BSD boot loader.

Going back to my original concept, I wiped the HDD clean and added a new GPT partition table. I created a EFI System Partition (512 MiB) and a 50 GiB partition into which I installed Windows. This was successful with Windows automatically adding another hidden partition of 16 MiB.

I then proceeded to install GhostBSD in UFS Custom Disk configuration. At this stage, my partitions looked like this (please excuse the Linux terminology).

/dev/sda1 512 MiB ESP (EFI System Partition)
/dev/sda2 50 GiB Windows
/dev/sda3 16 MiB Windows (hidden reserved)
/dev/sda4 30 GiB BSD (UFS+SUJ mounted as /) ada0p4
/dev/sda5 2 GiB BSD swap ada0p5

Code: Select all

The remainder of the HDD was left unallocated, to be used later for the Linux distros and a common data partition. The GhostBSD install appeared to be successful, but on rebooting there was no way to boot into GhostBSD. This first install was done selecting the "FreeBSD UEFI loader only". I repeated the install, this time selecting "Setup Refine boot manager" (Is this a typo? Is it meant to be the rEFInd boot manager?). I redid both installs again, with the same result. I then repeated the GhostBSD installs for a fifth and sixth time. I still couldn't boot into GhostBSD. There is no entry for it in the UEFI boot manager, no relevant folder in the ESP (but see second paragraph below), and no other type of menu to select which OS to boot.

After re-reading both the GhostBSD and FreeBSD installation guides, and fruitlessly searching this forum and the internet generally for a solution, I decided to carry on and created two more partitions, a / and a swap, into which I installed Linux Mint. In Mint I was able to mount the GhostBSD partitition (/dev/sda4). I confirmed there was a /boot folder which contained both loader & loader.efi files. Using efibootmgr I confirmed that there was no entry for GhostBSD in the UEFI, only ones for Windows and Mint.

I investigated further using Mint. After mounting the ESP, in the folder /boot/efi/EFI/Boot, there is a file refind.conf. At the tail of this is a GRUB-like entry for GhostBSD. I copied this and added it to my grub.cfg in Mint. As root, I then ran update-grub. However, this didn't work either. GRUB gave me the following:-

error: can not find command `loader'.
error: can not find command `icon'.

Updating Grub separately detects GhostBSD as an "unknown Linux distribution on /dev/sda4", but as I was already aware, this does not automatically add a menu entry. I also tried to boot using the following entries gleaned from various sources, but again none worked.

Code: Select all

menuentry "GhostBSD - refind way" {
    loader \EFI\Boot\bootx64-trueos.efi
    icon \EFI\Boot\icons\os_ghostbsd.png
}

menuentry "GhostBSD - shotgun way" {
    set root=(hd1,gpt4)
    chainloader +1
}

menuentry "GhostBSD - easy way" {
    insmod ufs2
    set root=(hd1,gpt4,a)
    kfreebsd /boot/loader
}

menuentry "GhostBSD - direct way" {
    insmod ufs2
    set root=(hd1,gpt4,a)
    search --no-floppy --fs-uuid --set 5d2a4b064b8c7824
    kfreebsd /boot/kernel/kernel
    kfreebsd_loadenv /boot/device.hints
#    kfreebsd_module /boot/splash.bmp type=splash_image_data
    set kFreeBSD.vfs.root.mountfrom=ufs:/dev/ada0p4
    set kFreeBSD.vfs.root.mountfrom.options=rw
}
Lastly from previous experience, I know I could install the rEFInd boot manager in Linux Mint, and use that to boot GhostBSD. However I would rather not complicate the situation by adding yet another boot loader/manager to the several I have already. I would rather understand where I have been going wrong so far.

To summarize:-
1) Why could I not dual-boot GhostBSD with Windows 10? What did I miss or do wrong?
2) Can I now install a boot loader/manager from the GhostBSD LiveUSB and would that also boot Linux?
3) Could someone please give me the correct syntax of a menu entry for GhostBSD in GRUB with Linux?

Thanks in advance.
