I suggest you visit the website of the manufacturer of your computer to search for info on creating a restore disc from the recovery partition on your hard drive.
When I upgraded the hard drive in my laptop, I used the software from Western Digital, which was a special (Western Digital) version of Acronis TrueImage software, to clone my old drive to the new one. To to this, you will need an external enclosure to put one drive in. Alternatively, you could use a USB Hard Drive Adapter; however, an external enclosure would allow you to use your old hard drive as an external hard drive.
