Put it in the CD drive. Reboot.

One frequent error that makes the CD unbootable is that people burn the *.iso image to CD as a data CD. You need to "Burn Disc from Image" or the like depending on what burning software you're using.

runing it as a live cd will not mess up my current system?

With computers, there are no guarantees---always have important data backed up.
Running from a CD does not normally do anything to what is on your hard drive

Not normally. However, I have seen one scenerio where you can get surprized (no harm done, but the surprize itself generates a little pucker factor).

Code:

(1) You boot with a LiveCD.



(2) It automatically mounts your existing partitions (many, if not most LiveCD's will do this).



(3) Something locks up.  Xwindows perhaps.



(4) You say "No problem, it's only a LiveCD" and hit the power button to forcefully reboot.



(5) It does, but now your harddrive's OS (Windows probably) complains that it must

    "check the disk for errors".



(6) You are scared.



(7) Nothing bad is found when the disk is checked, and the reboot then procedes normally.

The above happens because even Windows can tell that things were not shut down cleanly, so it wants to check the disk for errors "just in case".

A variation of the above can happen if your current harddisk OS is Linux, you boot a LiveCD that is using a different timezone offset than your harddisk OS, you reboot your harddisk OS cleanly, and you get a warning that the filesystem must be checked because it's "last mount time is in the future". The check turns up nothing bad, the last mount time of the filesystem is reset to normal, and then the reboot procedes normally.
