What follows is somewhat of a hack to install a VirtualBox virtual machine from an '''Usb''' stick instead of a '''Dvd''' or '''Iso''' image. An Usb install is impossible per se as '''the VirtualBox Bios does not support booting from an Usb device'''. A "lack" that limits user options when installing as well as when the machine is in need of a rescue system to solve operating system repair.

== RAW HARD DISK ACCESS ==

== Raw Hard Disk Access ==

Permits a guest system to access a host hard disk or a disk partition bypassing the host machine file system. Direct access is a '''VMDK file format only feature''', one of the many VirtualBox supported virtual machine formats. A VMDK image file is mandatory to take advantage of raw hard disk access. Once created, the image file can be used as any other virtual disk and assigned to a virtual machine.

== BOOT IMAGE ==

== Boot Image ==

In order to perform an installation from an Usb stick a boot image should be copied to the stick itself. Such images usually fill the whole stick despite of its partition count or its size. Given our final goal, we will presume that the device is used wholly and as such raw access for an entire hard disk will be configured.

== VIRTUAL DISK ==

== Virtual Disk ==

Creating a virtual disk from a hard disk in VirtualBox requires use of the '''VBoxManage''' command followed by a proper option list.

== STARTING THE INSTALLATION ==

== Starting the Installation ==

When the Usb boot stick is ready, start the virtual machine from the Gui. During the emulated boot phase press key '''F12''' to '''select the booting device'''.
