Since Ubuntu is my favorite operating system I installed it on my office Laptop initially in dual boot with Windows. I can do most of my office work like emails (in Evolution), creating and reading the documents (in Open Office) on Ubuntu. But we have many drawings in dwg and dwf formats and although, I could install dwg viewer on Ubuntu I could not find satisfactory solution for viewing dwf format. In addition Bank of Baroda Net Banking transactions require Internet Explorer and Microsoft Virtual Machine. I was using Windows for this purpose.
After briefly trying Wine I decided to install Virtual Box on Ubuntu and installed Windows in Virtual Box. I added dwg and dwf viewers in the Windows installation.
Now I can simultaneously use Ubuntu and Windows. See the Ubuntu and Windows running in two workplaces below:
