VMware Converter equivalent

[Mathieu Malaterre <mathieu.malaterre@gmail.com>]

Hi all,

  I recently bought a laptop with a microsoft windows 7 OEM OS. I
would like to convert into a virtual machine for later use in
VirtualBox.

* I tried using restore DVD, but upon installation within VirtualBox
it keeps on claiming an insane amount of disk space for installation
* I tried using VMWare Converter but the software fails miserably
during conversion (around 1% progress).

  Does anyone knows of any other alternatives software to convert a
physical machine to a virtual one ?

Thank you
