I am completely new to the concept of virtual machines and am trying to set up my first VirtualBox VM. Specifically I am trying to run Ubuntu as the guest on my Windows 7 host machine.
I'm at a stage where it's telling me that I have to partition my virtual disk in order to correctly install Ubuntu. I know this may be a stupid question, but I have so much treasured data on my hard drive, I'd hate to somehow lose it while partitioning my VM's disk!
If I move forward with this partitioning, does it just partition the free space I allocated to it when I configured the VM in the VirtualBox wizard, or do I run any risk (at all) of overwriting something on my Windows machine?
