Yeah. I thought it would just, y'know, clear it off if I installed Vista onto it, since it has things on it from two years and at least four installations ago on it that I'll never use. I didn't think of formatting it. Nope. Of course not. This is why you don't install stuff at 3am while 90% asleep, guys. So now, the computer asks if I want to boot "Windows Vista Home Premium" or "Windows Vista Home Premium." Which is fine because I've figured out which is which, but I'm pretty sure it's a bad thing to have it installed twice, right? I'm also paranoid of it thinking it's not a genuine copy because of it. Is there any way to full blown uninstall Vista from the other drive? Even after formatting the drive, it still shows up in the boot menu.
