[ubuntu] Windows 7 64 Pro via Virtual Box stuck "unpacking windows"

view story

http://ubuntuforums.org – Ubuntu 12.10 on Lenovo x230 Tablet I5 intel. Very new system, and older retail box DVD of Windows 7 Pro 64bit. So far I have downloaded Virtual Box from the Ubuntu Software center and then started installing it via Gui. Windows starts its install process but stops during the unpacking process. I left it for 3 hours and it stayed unpacking. How can I get windows/virtual box past this stage of the install? (Hardware)
