* Make sure you have the ''syslinux'' package installed on the operating system that you will use to prepare the Live USB image. It is recommended that you also have the ''isomd5sum'' package installed. The ''cryptsetup'' package is another option potentially used by the "livecd-iso-to-disk" installation script. (On Ubuntu, <code>sudo apt-get install syslinux isomd5sum cryptsetup</code> will install the packages.)

* It might be needed to uncomment 'SAMPLE FILE' in /etc/mtools/mtools.conf to make syslinux work,at least on gentoo.

**''isomd5sum'' is needed for the recommended verification step, which checks that the .iso file is complete after its travels. If there is a problem with the .iso file, the script will exit and provide a failure message.  The verification step can be bypassed by using the <code>--noverify</code> option.

**''cryptsetup'' is only needed for the option to provide password protection and encryption for the persistent /home/liveuser folder. It is not necessary if one applies the  recommended <code>--unencrypted-home</code> option. The <code>--unencrypted-home</code> option is preferred because the reduced overhead improves robustness with the compressed ''squashfs'' file system employed by the Live USB deployment.

* 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:
