I have an issue while installing in "Installation Type". Since it is a virtual machine with its own virtual disk, should I choose "Erase disk and install Ubuntu" or will it have an impact on my actual disk with Win7? https://i.stack.imgur.com/EBXXR.jpg
Secondly, if I choose this option there is a pop-up, what does it mean and am I supposed to accept it? https://i.stack.imgur.com/lS8NU.jpg
Thank you.
