Gosh I was so confused today. I am not very good with computers and I am now just learning how to use some of the more advanced features of the computer. My sister had to show me a lot of the features. I did not know what fixmbr was but now I do. It is really important to know if you are using a computer. Well from what I was told at least. I learned how to completely reformat a computer. I will need to remember that when I sell my laptop on the computer. I do not want people knowing my information.
