I had recently needed to reinstall my operating system because it was screwed up. I reinstalled Windows home Edition, and now I get a dual boot screen every time I try to reboot. It says that I need to choose an operating system, but they are both the same exact one. It says I can choose from XP home or XP Home. I have been using the top one, but I am not sure if it has used the other operating system after the 30 seconds. So, my problem is this... Which one is the most recent and which one is the corrupt old one. I want to delete the old one to save on disc space, but it also seems like they are interchangable. What I mean is that I didn't have to install Steam for half-life 2 on my computer when I reinstalled. It was like it was still there.
If you have answers to the following questions, I would truely appreciate it:
1. How do I know which of the two is the one I want?
2. How do I make sure I have what I need from the old.. If that is possible
3. Is it taking up disk space and RAM? Should I worry about it?
