Nowadays when you buy a laptop or computer it will not come with a recovery disk. Actually, it has been like this for several years; at least for most laptops/computers. For example, my IBM ThinkPad T40 from 2003 does not have a recovery disk.
The "recovery disk" is on a hidden partition of the hard drive. You need read through the instructions that came with your laptop to find out how to do a fresh reinstall of Windows 7. For example, if I wanted to reinstall Windows XP on my ThinkPad I would have to press the "Access IBM" button, and then to the appropriate option.
also check though ur start menu for something that says "create recovery disk" which should make a bootable manufacture specific reinstall disk set. could be under the assist program or manufacture specific info/help section
