I want to install FreeBSD alongside my Debian, Arch and Kali installs, but I'm having problem creating a bootable USB. I followed the instructions given in the BSD handbook, but my PC doesn't recognise the USB during boot process. I tried

$ chainloader (hd0)/boot/boot1.efi
$ boot

at the grub prompt but it gave an error which says something like 'zfs couldn't find pool;ufs couldn't find slice; can not load loader.efi;'

loader.efi is also in the (hd0)/boot directory. Do I need to format the USB drive as USB or ZFS prior to image burning, or do I need to format the partitions on which I'm going to install BSD as UFS or ZFS?

My laptop is an HP-15ac650tu. These are the two images I used, the result was same both times:



NOTE: I have read the other threads with similar names, and they do not mention the error I'm getting.

  • You said you are using loader.efi. Does the computer you are using have EFI firmware? What computer do you have?

  • Can you add the link to the FreeBSD.iso used?

  • There is a memstick version - see my answer on how to create the USB device.

First, off, doing a quick check of the User Guide, it appears that your computer uses a BIOS, not EFI.

That said, you are probably using the wrong FreeBSD image to begin with. Download using your version of Linux, either of the following images specific for creating a USB installer

Once you have the image, use dd to write the image to the USB drive

To do this, you will need to know the device identifier of the USB drive (i.e. /dev/disk0, /dev/disk1, etc.)

Once you know this, execute this command:

dd if=FreeBSD-VERSION-RELEASE-amd64-memstick.img of=/dev/diskX bs=1M

Where VERSION is the version of FreeBSD that is downloaded and X is the device number of your USB drive.

You should be able to boot from the USB after this.
