I've been dualbooting Windows 7 and Manjaro for about a year now, and I'm getting tired of rebooting every time I want to switch operating systems. I recently heard about the Virtualbox option to run an existing partition in a VM, so I decided to try that. To clarify, I have 4 partitions on the hard drive: Manjaro, a boot partition, Windows and a data partition for windows which contains the User folder, and probably needs to be available on boot.
