So my dad finally got the new PC. A Packard Bell... 300gb HD 2GB Ram Intel Pentium D. But the nice people at the store thought we were a newbie family and when I booted it up, I was presented with TONS of junk and free trials and net nannies... and AOL. So I formatted. But I'm having this problem. After the formating has finished, whenever I boot the PC up, it presents me with which OS I want to boot up. One is Windows XP from when I installed and the other is the previous Windows XP before I formatted. How do I get rid of that, "which OS do you want to boot up message?" from popping up again?
