VBox new install partioning

[ravirtual]

When installing Virtual Box for Kali Linux, I stopped at the screen that asked about partitioning. I want to install Virtual Box into my existing Win7 system. It has one hard drive. During install there is a box labeled Create Virtual Hard Drive. Can this overwrite my Win7 system? Assumably this step will create some benign virtual space that it needs somewhere on my Windows hard drive without causing any damage to me primary Win7 system? Thanks for your help!

No, the "virtual" OS occupies (usually) a single VDI file up to the maximum size that you declared during the virtual HD creation (if you've accepted the defaults, which are type: VDI, size: 8GB, kind: dynamic). To your host Windows 7 it looks like a simple, largish file. That's it. It doesn't modify in any way, shape or form your host.
