Dear Everybody Today, I have tried to virtually install Kubuntu 10.04 inside a Kubuntu 10.04 environment - via "Virtual Box", which I quickly installed without problems from the regular repository. The CD with the WIN7 software that has been delivered with my netbook, is a so-called "recovery" CD. The OS files VirtualBox needs to create the guest Win7 OS, are not accessible - apparently because of some software which makes them inaccessible. I am using an external "LaCie" CD/DVD drive which works perfectly well for various other purposes. So, the failure of my attempt to create a virtual Win7 guest OS has been created by one or more software problems. I am wondering whether it is possible to find one or a few "workarounds" for those problems. In a PDF document I show screen shots in order to try to make you understand what goes wrong exactly. Via this link you can find the document: <a href="http://rainbowgathering.eu/VirtualBox-Win7.pdf">http://rainbowgathering.eu/VirtualBox-Win7.pdf</a> I hope some amongst you can give me a clue. Respectfully yours, Bas Roufs.
