I just installed FreeBSD 10.3 on an HP 450-a114. The install went smoothly with no issues. The machine has Windows 10, Linux Mint, and an LFS distro. In the past (on the older BIOS-only machines), all I have had to do is add a menu entry to a grub file, run update-grub, and then FreeBSD would boot Using grub2. The machine I am on now is uefi, and I cannot get FreeBSD to boot. Windows and Linux boot fine though. Everything is on a single drive. Here are my partitions:

/dev/sda1 -> Some uefi partition (label: /boot/efi)
/dev/sda2 -> Some Windows partition
/dev/sda3 -> Windows 10
/dev/sda7 -> My LFS distro
/dev/sda6 -> Linux Mint
/dev/sda8 -> Some efi partition installed by FreeBSD (label: EFI)
/dev/sda9 -> FreeBSD
/dev/sda10 -> FreeBSD swap
/dev/sda4 -> Windows recovery image
/dev/sda5 -> Windows recovery image.

If anyone needs any type of command line output, I will be happy to post it.

So /dev/sda1 is probably the EFI system partition used by Windows, LFS and Mint. You can boot into them because the relevant files for these operating systems are inside /dev/sda1 and so is GRUB. Therefore, GRUB can detect them.

However, the FreeBSD installation has created it's own EFI system partition in /dev/sda8 and this is the reason why update-grub doesn't work because the GRUB in /dev/sda1 isn't able to find the relevant EFI files in /dev/sda1.

You can try moving the relevant EFI files in /dev/sda8 created by FreeBSD to /dev/sda1, edit them to reflect the changes, and try running update-grub again.

On another note, why install so many operating systems on so many partitions? Using a virtualization solution like qemu or VirtualBox might be a better option.

  • I will try that. I am very familiar with virtual machines, but my computer is not the highest quality, so I can only run 32-bit virtual machines, and even these are SO slow.

  • So, I just went into the machines boot device options as I was booting, I found a weird efi entry, hit, and it booted (I had not moved any files like you suggested). Is there are way to get grub to do the same thing?

  • @pdf4664 Yes, you can use your UEFI boot menu to boot into either of the operating systems. You can try to move your FreeBSD EFI files in /dev/sda8 to /dev/sda1 and run update-grub in either Mint or LFS. I think that should work.
