Download that, create a bootable floppy from the download. Then make sure both the new and old drives are connected, boot from the floppy disc and follow the instructions. It's pretty simple, just make sure to setup the new drive as C: not additional storage and it should copy the files at the end of the process. Once done, just unplug the old drive and it should boot from the new one, then just check everything is alright and present.
Although it's always worked for me, it's common sense to backup your important data first! Saying that however, the data will still be on your old drive after you finish.
Hope this helps!
