I am not sure about safe mode and I am not home infrom of my computer. Seems like the first thing I see on my screen is some basic computer info in upper left hand corner, then it asks if I wants to reboot using cd-rom or hard drive(I think), I put my disk in and set up begins, I get to the part of product key and I dont have it. I have found a way to get it but I need to be able to get to the start, run redegit....( i'm sure you know what I am talking about there). Man, I am at a loss of what to do.....thank you for any help you can give me....
