You should see output that looks like this:

* Also, check to see that you do not already have an existing bootloader (such as GRUB) in the MBR of your stick. (If you have not previously used this stick as a live boot, you can skip this step.) To be sure that the USB stick's MBR is wiped clean, overwrite it completely using:

: <tt>dd if=/dev/zero of=/dev/~~sdb~~ bs=446 count=1</tt>

: <tt>dd if=/dev/zero of=/dev/sd''b'' bs=446 count=1</tt>

* Change mode to make the script executable.

: <tt>chmod +x livecd-iso-to-disk.sh</tt>

* Run it as root, making sure to pass the correct USB device and to set overlay and home size appropriately, depending on the stick size.

: <tt>sudo ./livecd-iso-to-disk.sh --overlay-size-mb 300 --home-size-mb 160 --delete-home --unencrypted-home soas-beta.iso /dev/~~sdb1~~</tt>

: <tt>sudo ./livecd-iso-to-disk.sh --overlay-size-mb 300 --home-size-mb 160 --delete-home --unencrypted-home soas-beta.iso /dev/sd''b1''</tt>

The ''livecd-iso-to-disk'' installation has the advantage over the ''liveusb-creator'' installation method by allowing a persistent /home/liveuser folder with the <tt>--home-size-mb ''NNN''</tt> option. This feature would allow you to update the OS image while keeping the user files (by running the script against your existing installation but <u>leaving out</u> the --home-size-mb NNN option).

* The <code>--delete-home</code> option is used to avoid an error message while requesting both a new home (with <code>--home-size-mb</code>) and a persistent home (indirectly with <code>--unencrypted-home</code>). You wouldn't use the --delete-home option on an upgrade of the operation system only.

Depending on the size of your ~~usb~~ stick, you may have to decrease <code>--overlay-size-mb</code> and <code>--home-size-mb</code> values (example, for 1 GB stick, use 200 for each).

Depending on the size of your USB stick, you may have to decrease <code>--overlay-size-mb</code> and <code>--home-size-mb</code> values (example, for 1 GB stick, use 200 for each).
