I have installed VMWare. I have got three Fedora, Ubunta and Mandriva. I found my VM with Mandriva KDE. That is the best. The interface is the most like with Vista. The "Start" button menu structure is very similar and is similar with the user document structure of Vista, such as "Download".
Moreover, the actions are very smooth with 512 MB VM. That is an good option.
I have tried to build a linux laptop for my test purpose. No Sucess at all. That seem to be the hard disk of my old laptop not working. Moreover, there are display and screen resolution issues. I can't get fixed. OK. The solutions I got my main PC is quite pwoerful it can handle the virtual machine. Thus, I tried VWMare workstation. That is very good. It is stable. Because that is virtualized, so no problems on drivers. My Ubuntu supports the VWMave virtual hardware!
