+You can't just boot from a USB Stick with VirtualBox because it's BIOS does not support USB.
+However, you can still get it to boot from USB.
+But first, you have to convince OS X not to remount your USB Stick everytime it's `/dev/diskX` file is accessed.
+
+To do this, you need to know the Label of your USB drive (with spaces escaped with `\`) and it's filesystem type (fat32 in this case).
+
+Create the `/etc/fstab` file, if it doesn't exist already, and mark your stick as `noauto`:
+
+<pre class="sh_sh">
+sudo touch /etc/fstab
+sudo nano /etc/fstab
+LABEL=yourUSBstick none fat32 rw,noauto
+</pre>
+
+Then create a VirtualBox Disk Image, pointing to the block device file of your USB stick. Use diskutil to find out the device file name.
+
+<pre class="sh_sh">
+diskutil list
+sudo VBoxManage internalcommands createrawvmdk -filename rawUsbStick.vmdk -rawdisk /dev/diskX
+</pre>
+
+Now, run VirtualBox as root
+
+<pre class="sh_sh">
+sudo /Applications/VirtualBox.app/Contents/MacOS/VirtualBox
+</pre>
+
+Create a new Virtual Machine, using the .vmdk file created before as virtual hard disk drive. Boot it, and...
+
+Done! :)
