How do I transfer all my information including OS from one HDD to another HDD?

Question

I'm about to upgrade my compaq running windows xp hard drive. From 20 gigabytes to 120 gigabytes. I dont have the origonal CD's that came with this computer and definetly dont want to buy windows xp all over agian, and then have to install drivers then transfer files. so my question is, what software (free preffered) can i use to burn all my information to a disc to install into my new drive. i need the disc to be able to boot on its own offcourse and then copy all my information to the new drive, then im hoping i just simply shutdown my computer, pull out the disc and turn my computer back on and it should be running exactly the same, only diff is the extra 100 gigs. (thats how it works im guessing? am i right?). It this isnt possible if anyone can help me with any other way but i only have this laptop an thats it. thanks guys!!

This will do it, but you will need to resize the partition after....

there are programs that you can use to make a image of your computer and it will let you install it on a bigger hard drive for example norton ghost is used just for that
