Yes windows has a back up wizard - here are HP links about how to do it.
I would print or take notes on it, and read through it a few times to fully understand it, but it is fairly easy just follow the promps and use your notes.

I gave a list of info links so you can look through all to find the ones that are clearest for you.

Ive never done anything like it on a hp - but it should be straight forward.
esp if you only have one hard drive, I don't know if you have partitions on it - other than the restore partition - i think hp has that saved for the restore files.

a partition is a hard drive that is divided into sections and will have a label c, f,g,h, etc.

cd & dvd are usually d & e drives
