Guys, I am torn. I have a laptop with Win8.1 which I cannot remove because others in the family are not familiar with Ubuntu and they do not want to learn it. But, I want to use Ubuntu as my primary OS of this PC. What do you think is the best solution? Dual boot (maybe with a third partition where to store all data, documents, etc) or Ubuntu running in a VM with Windows as host? Another problem is how to secure the data (which either OS should read/access) with some encryption.... Thanks much.
