So my wfie's boss hears I am good at computers and sends his laptop home with her for me to fix. So I do not get her in bad light, I need a little help fixing his computer. I know how to re install windows which is what I think I need to do. His computer will not boot, you see the windows loading screen, it does it things, and right before its done loading, blue screen of death with an error message, and starts over. I looked at it for 5 mins when I was home on lunch, couldn't tell what the message said it was so fast but I am pretty sure I just need to reinstall windows right? If yes, how can I backup everything on his computer so I do not erase it all in case he didn't back it up on his server. By the way, I tried booting from Safe mode and last best configuration, all had the same result, blue screen of death for 2 seconds and bam re starting windows. It is Windows 2000 by the way. This is also my first post.
