Ubuntu in external drive - want start internal Vista

[marcopogo81]

Hi all,

I'm new in this forum..I'm sure i can found the solution at my problem.

I have installed ubuntu 8.10 on external usb drive (320gb) and work very fine, but my enterprise VPN need Vista because my enterprise is microsot partner and VPN work only with vista..

I want to run the SO (Vista) that i have preinstalled on the laptop and is in the internal HD in the virtual box.. anybody can tell me how can I do or where I can found a solution?

Plz!!

Tnx Marco
