Writing the snapshot image so it boots

  • I'm trying to write out the image on a mac to a USB flash drive using this command:

    cat pfSense-CE-memstick-2.4.4-DEVELOPMENT-amd64-latest.img | sudo dd of=/dev/disk2 bs=1m

    It writes fine and I can mount the resulting disk. However I'm unable to boot from it. Using the same procedure on a release version instead of the development version gives me a bootable drive. Is there a different procedure to use for the development version? I've also tried other images that are bootable and they boot and work fine (ie linux images).

    Just use www.etcher.io

    (The command would be sudo dd if=pfSense-CE-memstick-2.4.4-DEVELOPMENT-amd64-latest.img of=/dev/rdisk2 bs=64k)

    The 2.4.4 dev images are hybrid (ISO and memstick image). You could possibly be running into some sort of incompatibility there.

  • Thanks for the reply, I did try it that way as well and same result:

    sudo dd if=pfSense-CE-memstick-2.4.4-DEVELOPMENT-amd64-latest.img of=/dev/rdisk4 bs=64k

    I can see in Disk Utility the disk is an ISO9660 drive. This is the memory stick. Still can't boot it though. I also tried switching the machine from Dual to Legacy in the BIOS but no luck.

    I won't be able to be of much help but for someone else you probably want to detail what you are trying to boot it on in as much detail as possible.
