Good point, Fernando. Also, it is true that you can use a Live CD for booting into a Linux environment even though your disk may have only a Windows, or some other, file system and, therefore, be inaccessible to the virtual OS, or the disk may not yet have been formatted. Okay, knowing that this would not make VB go haywire, I tried it out and all is good. It works just fine without the virtual disk, and as a matter of fact it even advised me, when I was setting it up, that the lack of a disk would now require me to use only a live CD in this VM. So, this is a good way to save disk space and save time. Awesome. Now, the next major hurdle to overcome in this VM's scenario is finding a good resource explaining how to make use of a writeable DVD drive on the host from within the guest OS. ------------------------------------------------------------------------------ Everyone hates slow websites.
