I was wondering if anyone could help with this matter. I have Windows Xp Home Edition, and a 40gb harddrive, and I keep getting an error. Before last Christmas, I had Windows XP Pro edition, and I had been using my computer alot. Then one day, I get home from school, turn on my computer, and instead of booting, it says "Disk boot failure. Insert system disk and press enter." I do not remember anything I did that could've caused this error. I then booted from a CD called Bart Ghost" and apparently my partition had been erased.Unfortunately, the windows installation copy that my dad had had a scratch on it, so after a couple of weeks, I installed Windows XP Media Edition. I was doing good for a while, then one day, I get the same error. We had returned the media edition software to a friend, but my dad found the Windows XP Home Edition disk, so I installed that. I thought that was the end of that error, but about 31 days later, I get the same exact damn error. My dad and I cannot figure out what it is. Do I have to use a program called KillDisk, and completely wipe my harddrive, like my dad suggested? One quick additional note: I have been downloading anime episodes in .flv format at school, and taking them home on my jumpdrive, and storing them on my computer. Each one is about 100MB large. Maybe one of those files may have corrupted my harddrive?
