Then things went terribly awry. I asked my brother who's a self-proclaimed tech genius how to uninstall Windows XP, because trying to do it through the Add/Remove Programs menu like the Help files say did not work (XP did not show up as a program there). He told me, then, to delete the unnecessary WINDOWS folder on that drive of mine. I asked him if he was sure that would work, and he said he was.
Well, of course, it didn't. I have deleted the OS, but, at startup, I still have the option of choosing to load the now nonexistent OS. If I try to load it, of course, I get an error that causes the computer to restart...
Augh, yes. It's stupid, but maybe it's simple to fix.
