Its very easy to do!
First, welcome to the world of Linux! For starters, there will be no command lines, and the install is very guided. Its very similar to a game, if you wish to compare it like that. Just point and click.
I highly recommend Linux Mint.

All you have to do, is burn the CD so it is bootable (just google "make linux mint cd"), and then go into your boot menu and have it boot from the CD drive. I"m not sure what it is for your laptop, but when you get the BIOS splash screen, just hit F12. Then choose the CD drive. The rest will be very guided.
Come back if you need help!
