The GNOBSD-USB-Image is the same like the LiveDVD-ISO.

Here is an example how you can copy the image to an usb-stick on an ubuntu-system:

  1. Plug in the usb-stick, start a terminal and execute the command “dmesg”.
    You should see some output like this:
    $ dmesg
    …
    [620707.228637] sd 10:0:0:0: Attached scsi generic sg5 type 0
    [620707.229574] sd 10:0:0:0: [sdf] 7897088 512-byte logical blocks: (4.04 GB/3.76 GiB)
    [620707.232667] sd 10:0:0:0: [sdf] Write Protect is off
    [620707.232678] sd 10:0:0:0: [sdf] Mode Sense: 00 00 00 00
    [620707.232684] sd 10:0:0:0: [sdf] Assuming drive cache: write through
    [620707.242952] sd 10:0:0:0: [sdf] Assuming drive cache: write through
    [620707.242964] sdf: sdf1
    [620707.376996] sd 10:0:0:0: [sdf] Assuming drive cache: write through
    [620707.377014] sd 10:0:0:0: [sdf] Attached SCSI removable disk

    => We need the raw-device. In this case it is sdf.

  2. Write the image to the usb-stick:

    $ sudo dd if=gnobsd46-i386.img of=/dev/sdf bs=1M

    “if=” is the file you want to use
    “of=” is the path where the input file should be dumped to.

    Attention: Be sure that you are writing to the right device

  3. After the image has been written to the usb-stick you can boot and install from it.
