...or maybe, just maybe, you're sticking your nose where it doesn't belong. Maybe your Aunt indeed has two copies of OS. We know we do: 1st for Mainstream Usage, 2nd for Testing and performing any high-risk bussineses. 3rd serves as a backup to troubleshoot why one of the previous encountered problems or didn't booted at all (4 HDDs totalling 360 GB... we can afford it). But, on the other head it all comes to the tone of your aunts voice when she addressed you with that "issue" (if she addressed you at all).
