title: How to install FreeBSD on x86 GNU GRUB payload
x-toc-enable: true
...
FreeBSD might show graphical corruption during bootup. You can fix this by
altering the order in which kernel modules/drivers are loaded. First, try moving
video to an earlier stage on the boot process, or try moving it to a later stage
instead. With this, you should be able to get a working display.
freebsd.img is the installation image for FreeBSD. Adapt the filename
accordingly, for whatever FreeBSD version you use.
Prepare the USB drive (in FreeBSD)
----------------------------------
[This page](https://www.freebsd.org/doc/handbook/bsdinstall-pre.html) on
the FreeBSD website shows how to create a bootable USB drive for
installing FreeBSD. Use the *dd* on that page.
Prepare the USB drive (in NetBSD)
---------------------------------
[This
page](https://wiki.netbsd.org/tutorials/how_to_install_netbsd_from_an_usb_memory_stick/)
on the NetBSD website shows how to create a NetBSD bootable USB drive
from within NetBSD itself. You should use the *dd* method documented
there; you can use this with any ISO, including FreeBSD.
Prepare the USB drive (in LibertyBSD or OpenBSD)
------------------------------------------------
If you downloaded your ISO on a LibertyBSD or OpenBSD system, here is
how to create the bootable FreeBSD USB drive:
Connect the USB drive. Check dmesg:
dmesg | tail
Check to confirm which drive it is, for example, if you think its sd3:
disklabel sd3
Check that it wasn't automatically mounted. If it was, unmount it. For
example:
doas umount /dev/sd3i
dmesg told you what device it is. Overwrite the drive, writing the
FreeBSD installer to it with dd. For example:
doas dd if=freebsd.img of=/dev/rsdXc bs=1M; sync
You should now be able to boot the installer from your USB drive.
Continue reading, for information about how to do that.
Prepare the USB drive (in GNU+Linux)
------------------------------------
If you downloaded your ISO on a GNU+Linux system, here is how to create
the bootable FreeBSD USB drive:
Connect the USB drive. Check dmesg:
dmesg
Check lsblk to confirm which drive it is:
lsblk
Check that it wasn't automatically mounted. If it was, unmount it. For
example:
sudo umount /dev/sdX\*
umount /dev/sdX\*
dmesg told you what device it is. Overwrite the drive, writing your
distro ISO to it with dd. For example:
sudo dd if=freebsd.img of=/dev/sdX bs=8M; sync
dd if=freebsd.img of=/dev/sdX bs=8M; sync
You should now be able to boot the installer from your USB drive.
Continue reading, for information about how to do that.
Installing FreeBSD without full disk encryption
-----------------------------------------------
Press C in GRUB to access the command line:
grub> kfreebsd (usb0,gpt3)/boot/kernel/kernel
grub> set FreeBSD.vfs.mountfrom=ufs:/dev/da1p3\
grub> boot
It will start booting into the FreeBSD installer. Follow the normal
process for installing FreeBSD.

Troubleshooting
===============
Most of these issues occur when using libreboot with coreboot's 'text
mode' instead of the coreboot framebuffer. This mode is useful for
booting payloads like memtest86+ which expect text-mode, but for FreeBSD
it can be problematic when they are trying to switch to a framebuffer
because it doesn't exist.
In most cases, you should use the corebootfb ROM images. There ROM images
have `corebootfb` in the file name, and they start in a high resolution frame
buffer, provided by coreboot's `libgfxinit` library.
won't boot...something about file not found
---------------------------------------------
Your device names (i.e. usb0, usb1, sd0, sd1, wd0, ahci0, hd0, etc) and
numbers may differ. Use TAB completion.
