My laptop broke a few months ago and the hard drive had to be replaced, and I was told by the guy who did it that I needed to put in the CD that came with the laptop and then it would be fixed. However, I didn't get a CD with my laptop so I ordered one from HP.
When I put the CD in though, it just says "invalid system disk". I have had the disk replaced twice so I'm quite sure it's the right one, but I don't know what to do!
I would really appreciate some help!
