You should be able to use the boot disk without harming your system. You won't (obviously) be able to use the images from the old machine.
Version 8 does not support SATA hard disks, and this may be a problem if the laptop is new.
There is no reason not to make a new startup disk on the new machine - except for the massive expense of a blank cd, and the 2 minutes time involved!!! Indeed, it is always a good idea to make the cd in the machine to be used.. Rarely, but occasionally, a cd written in one machine is less readable in another.
